Losebag 

A person who loses so hard, they metaphorically morph from a person-shaped bag of meat and blood and stuff, and instead become a big baggy blob full of nothing but lose.

lose bag 

noun a person who has no real friends their own age and therefore hangs out with their kids friends or their siblings friends (not to be confused with a pedophile, milf, cougar or a douche bag, though loser may be an acceptable synonym)
