Coventry Twos
Due to Coventry's skank-whore reputation this is the name given to "twos" (the sharing of a cigarette in a 50:50 fashion) except that here in the W-Midlands Coventry Twos implies that the person sharing (i.e. the badboy who didn't pay for the tabacco product) takes way above their 50% entitlement. More of a 85:15 cut.
Person A: Can I have a drag or twos on that, ta?
Person B: Yeah! Sure... Right... So you can Coventry Twos me...
