Persuading people to do something they don't want to do, then when they finally get into it, fuck off and leave them to do it by themselves.
"Dude, you hear about Alex last night? He told his friends he wanted to go out, got them drunk and then went to bed"

Someone who is just completely terrible at something... Sports, for example. Can't play, misses the ball all the time, scores numerous points for the other team. Usually a nice guy, moderately intelligent and good natured; you just don't want him on your team. A curse will follow you should he be placed there.
