Demexit - Democrats that vocally declare one's intent to depart the United States for England if they don't get their way, but then indecisively delay or quietly avoid departure. Would rather live in England drinking piss warm British beer and eating greasy Gordon's fish & chips.
Herbie hesitates going full Demexit for fear of the pairing of warm beer and cold fish.
demerit points are lost when a driving offense is committed. ie. speeding, driving through a red lightcamera, drink driving etc.
But in a colloquial context, that of V plates, they refer to other sexual acts that have been committed (apart from the big one). comparable to 'the bases' or 'scoring'.
1:"Do you still have your V plates?"
2:"Yeah, but i've lost a couple of demerit points tho... ;) "
