A very pretty, kind person. Usually is outgoing and athletic. Also is smart, funny, and cool. Does not like people calling Seko a Pyscho Seko.
"Hey, what's your name?"
"Haha, Pyscho Seko"
This word comes from the 'Tongan' language: the word "seko" means shit.
eg: I seko in that tree = I took a shit in that tree.
