Someone who is called Leifur is usually a very cool guy. Leifur is usually tall and skinny yet somehow eats a lot but is always slim.
Guy 1 - Hey Leifur you're really skinny, you know that?
Leifur - yeah...

Get the Leifur mug.
A wet fuckboy / someone who is more interested in unimportant garbage than in having a life.
Guy 1 : Hey dude you wan't to go grab a drink or something after work?

Guy 2 : Nah man I have to go and inspect my new CS:GO knife later.

Guy 1 : Wow man you're such a leifur.
