the.com/cap
The humble lid that became a lie, then a flex, all in one syllable.
means A close-fitting head covering or protective top for something, and in recent slang, a lie — with 'no cap' meaning 'no lie, for real.'
from From Old English 'cæppe,' meaning a hood or cape, borrowed from Late Latin 'cappa,' a head-covering or cloak — the same root that gives us 'cape' and 'chapel.' For centuries it stayed literal: the thing on your head, the lid on a bottle, the upper limit of a number. The slang sense of 'cap' meaning 'lie' is far newer, rising through African American Vernacular English; the popular link is to 'capping' as a tradition of boastful exaggeration in Black oral culture, where to 'cap' was to brag or talk big — and from there, to lie.
