Binhead is a term used to describe a smoking game in which the loser must accept a forfeit.
The game uses a pint glass which has a sheet of smoking papers held taught over the top by a hair ban, resembling a drum. Then a 5p piece is placed on the center of this sheet. The players then take it in turns to make a "burn" on the "bin". The player who's burn causes the 5p to fall is the loser.
