Lasse is the definition of a really nice guy who is so awesome that if you`d count to his awesomeness, you would never get finished. Lasse is also a word for an extremely smart guy. (His IQ is over 9000)
Wow that guy is so Lasse. I wish that i could be just as Lasse as him.

Lasse is one of the bestest people you'll ever meet, he is a fantastic gamer and overall the best guy ever. If you need someone to talk to, he'll pause the game just for you. Even if it's multiplayer, Isn't that crazy?? He is a really shy guy though, and very sensitive. He is really trustworthy and will NEVER leak a secret you've told him, you can tell him about anything. He won't judge you for what you look like or what you like, he loves to have internet friends but if you wanna meet up with him he'll be really scared. So if you ever meet with a Lasse, make sure to give him a gift and the biggest hug in history! He is also very adorable, so be careful of his adorableness!
Hey! Heard you met up with Lasse yesterday, how did it go?

Oh it went amazing! We went to his house and played videogames all night! I gave him a gift and he really really really loved it! He gave me the sweetest hug and had so much fun. Lasse is truly adorable.

Lasse is the hottest motherfucker you’ll ever meet. Just from looking at him will make you instantly start grinding on his face. Some say that Lasse has a higher IQ than Einstein, and he also has a large surprise under his pants ;). He is also rolling in e-girls...
Aaron: OMG have you seen Lasse he is so hot.
Lorenzo: Dudeeee I think I’m gay for Lasse.
Everybody else: I just creamed my jeans from looking at Lasse.

The kind of guy that would dedicate his life to maths and even go live in a cave so that he could study maths.

Lasses also knows the answer to everything, but they won't tell anyone.
Person 1: Hey, have you seen a Lasse somewhere around here? I forgot to do my maths homework.

Person 2: Try the library, I heard they set up a camp in there to study maths.

Person 1: Thanks man, I'll go have a look.

Person 2: Be careful though, they might try to convert you to become one of them.

Person 1: Ok, I'll be careful then, don't really fancy becoming a Lasse
