To kick someone to the curb means to reject, dismiss, or discard someone or something abruptly and decisively, usually as a justified response to bad behavior, incompetence, or worthlessness.
While standard dictionaries often define the phrase loosely as getting rid of anything “redundant or unwanted,” in natural English, the expression carries a strong implication of justified dismissal. People and objects are kicked to the curb because they have proven themselves to be trash, broken, or toxic.
Direct Meaning & Conversational Nuances
Understanding how native speakers use kick to the curb requires looking at why the action takes place:
Relationships: Firing Someone for Bad Behavior
You don’t “kick a partner to the curb” simply because you met someone else or lost interest. The phrase implies a harsh, unceremonious breakup triggered by betrayal, lying, cheating, or disrespect.
- “She kicked her boyfriend to the curb the moment she found out he was lying to her.”
Jobs & Business: Dismissal for Cause
In workplace settings, the phrase signals a sudden firing or termination resulting from poor performance, misconduct, or severe failure, rather than a polite, routine layoff.
- “The board kicked the CEO to the curb after the financial audit revealed major irregularities.”
Objects & Habits: Getting Rid of the Useless or Toxic
You don’t kick a perfectly functioning, extra TV to the curb; you kick an item to the curb when it is broken beyond repair. Similarly, people use it for bad habits or toxic influences that need to be eliminated.
- “That old lawnmower finally died, so I kicked it to the curb.”
- “It’s time to kick those bad eating habits to the curb once and for all.”
Active vs. Passive Voice: The Shift in Perspective
Much of the confusion surrounding this idiom comes from conflating its active and passive uses, which fundamentally changes whether the action requires justification:
- Active Voice (The Discarder’s Justification): Driven by the person doing the rejecting. From their point of view, the action is an assertive, necessary removal of bad behavior, poor performance, or uselessness (“I kicked him to the curb”).
- Passive Voice (The Victim’s Experience): Shifts the entire focus to the person being discarded. When the passive form is used (“getting kicked to the curb” or “I was kicked to the curb”), the action no longer requires that the rejection be objectively justified.
A person might be fired or broken up with for completely unfair, petty, or unsound reasons and still say, “I was kicked to the curb.” Even if the person doing the kicking felt justified in their own mind, the passive voice centers solely on the recipient’s feeling of being abruptly discarded, regardless of whether the reasons were actually sound.
Dictionary entries often misinterpret these passive, victim-focused statements as proof that “kick to the curb” means random or neutral discarding, missing the crucial difference between the two grammatical voices.
Origin & Physical Imagery: Setting Out the Trash
The idiom originated in mid-20th-century American slang and relies on the visual metaphor of residential garbage pickup:
- The Curb as the Trash Zone: The curb is the specific boundary at the edge of a street where homeowners set out broken furniture, refuse, and garbage bins for the city to haul away.
- Kicking vs. Placing: To place something on the curb implies care. To kick it to the curb emphasizes disdain, anger, and unceremonious removal, treating a person, habit, or object as literal junk.
Word Confusion: “Curb” as a Noun vs. Verb
Language learners often stumble over this idiom because the word curb functions as two completely different parts of speech:
- The Noun (The Physical Street Edge):In American English, a curb is the raised concrete or stone border along the edge of a street that separates the road from the sidewalk. This is the noun used in the idiom, specifically referring to the area where household garbage is placed for collection.
- The Verb (To Restrain or Control): As a verb, curb means to limit, check, or keep something under control (“You need to curb your temper” or “laws to curb inflation”). This verb definition has nothing to do with the phrase kick to the curb.
Regional Spelling: “Curb” vs. “Kerb”
To add to the confusion for learners of British English:
- American English: Uses curb for both the street edge (noun) and the act of restraining (verb).
- British / Commonwealth English: Distinguishes the two in spelling: kerb is the street edge (“kick to the kerb”), while curb is strictly the verb meaning to restrain.
