brown nose's definitions
hugely entertaining game played in drinking establishments. competitors take it in turns to display a small area of their genitalia through their trouser flies. the watching crowd then have to make their choice as to whether it is penis or testicle that has been exposed.
Boredom began to creep in, so a game of sack or shaft was initiated and quickly cheered everybody up.
