A form of masturbation where as soon as you cum you catch every single bit in the air with your other hand.

a karsten is a man that girls may call "awkward" at times. very shy. usually is found on by his computer where he lays listening to depressing music. wishing one day heill find true love. may have a hunched back and weird stance, women dont find a karsten atractive at all and sometimes can just be a buzzkill/cock blocker.
man- OMG its karsten that kids awesome i played WoW with him last night
women- ehhh i guess but sometimes i think what an awkward faggot sure he hasnt done anything wrong but still the only word that sums him up is awkward

A fuckboy who likes to always talk about other girls who got rid of them even though they never talk. A karsten kaminski will often never close his mouth and badmouth girls but constantly ask about them.
Wow he is such a karsten kaminski, I’m pretty sure he’s spent the whole English class talking about her

A Karsten Paulsen is a very smart person but one that often disappears suddenly from parties or other social gatherings. He has mastered the techniques of Houdini.
Man: “Hey guys, have you seen Karsten Paulsen?”
Other man: “No he pulled a Houdini…”
