A loser is the type of person that looks up “loser” on UrbanDictionary because they’re paranoid that they might themselves be one.
Andre’s a Class A loser - he’s literally sitting in his room right now freaking out about how all of the UrbanDictionary definitions of “loser” seem to be targeted at him…

A loser is someone who sucks at their sport, activity or hobby of choice. Generally, a loser will lose in the activity they are participating in. A loser is also someone lame or "uncool". In that sense, calling someone a loser would be saying they lost at life (because their life sucks).
"Katie couldn't find any toilet paper in her house. What a loser."
"Daniel was called a loser by his classmates because he wasn't very good at Pokemon"
"I can't finish this project in time. I'm just a loser."
