the worst type of a sucker. this is the dude that gets the raw deal. being a suckass sucker is something that nobody strives toward. somebody who gets stuck doing something totally boring while his/her friends are out doing something fun.
me: i just won a trip to vegas. i can take one friend. do you want to go?
friend: no, i can't. i have to babysit my cousin this weekend. i can't even watch the big game.
