A "loser" is someone who doesn't know what they have and fucks it up.

They are always making bad choices and fuck up their and everyone's lives around them.

They are Losers...

Also know as Dumb Fucks, Idiots, Fools, Dumb Asses, Dick Heads, etc.

A term used to reference cannabis/marijuana/weed.

A dumb bitch who uses the wrong hand to make the "L" symbol on her forehead.

As seen in the image above.

@ZubyMusic made this perfect distinction:

Don't use the term LOSER to refer to people who haven't made it yet.

Use it to refer to people who aren't even trying, but want to take shots at those who are trying.

A word used by many idiots to make them feel better about themselves while laughing at the misfortunes of many people who are many times
1. Depressed
2. Unable to raise their social status
3. Have gone through many hardships
4. Will probably be virgins for a LONG time
5. Have been tormented about being losers for all their life and don't need to hear any more bull shit.

Apparently it's anyone who doesn't spend all his time and money at the bar every night, someone who doesn't feel the need to get laid every five seconds, anyone who doesn't make a million dollars a day, someone who's at home for more than two hours a day, anyone over the age of 12 who still lives at home with his parents, and anyone who's ever touched a computer or videogame.
