Louser

Used to describe someone who causes a team to lose while playing a game. Someone who you can never win a game with no matter how hard you carry.

Person I: I can’t believe you made us lose that round Karen.. you’re literally the worst. You better have been trolling and not an actual louser.

louser

a louser (think houser but with a L) is someone who spends free time doing fuck all. this someone or someones could be doing Something, but that something is actually a meangless waste of time. the someone in question, has no life, no hobbies that matter and is hardly ever productive. lousers may think they help, just by being in the room, but in fact they do not.

nana what are you doing?
playing free cell.
tata what are you doing?
playing solitaire.
jeez! you guys are fucking lousers!
