2.
A term used for a very attractive young male with great manly features. Usually the most attractive person wherever they go. They never give a fuck either. In bed, they're considered kings of the jungle.
Fridend: Did you hear about that guy who did a triple front-flip off the empire state building and then went on to fuck that super attractive girl while her parents were in the house?

You: Yeah broseph, he's such a Senja.
