sleeping with a mate's girlfriend,
not returning a favour,
not returning a shout at the pub,
drinking the last half pot of beer out of a jug you didn't buy,
cheating - especially when when what you're doing is not competitive
tony: "that prick john always disappears when it's his turn to shout!"
1 - Ripping the final cone from a mix in which you didn't financially contribute towards.
2 - An empty mixbowl of any sort.
3 - Splashback whilst ripping a cone.
4 - Devouring all of the munchies which you didn't pay for (Redskins in particular)
5 - To sell me kiff, trying to pass it off as bud.
