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

As seen in the image above.

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.

You because you keep deleteing it

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.

loser – n. A person who has fallen off the social ladder, climbed down the social ladder, jumped off the social ladder, or just never bothered to climb the social ladder in the first place. Upon arrival on the ground, losers begin to befriend fellow groundlings and realize how much fun a person can have when gravity isn’t an issue. It is perfectly acceptable to insult losers, because they have nowhere to fall to and it won’t hurt much. They will end up laughing about it later, anyways. Every now and then, a loser will glance at the top of the social ladder, but it is never long before they realize how pointless and stupid the top of the ladder is.

Someone who purposefully teases and taunts another for their own enjoyment.
