A jokebag is a person who is a joke, full of shit, or simply someone you don't like, respect, or has traits of a doucher. Jokebags tend to be ignorant, clueless, and lucky too.

In poker a jokebag is someone who lucks out on you for playing shitty cards (also known as a luckbox). Jokebag can pretty much be used in many different reasons and context, thus making it the greatest word of all time.

Synonyms: Luckbox, n00b, Scrub
