A gok is a person who always thinks of himself in all situations. A gok is a person also being able to backstab or thief a close friend to gain advantage of it, most likely money. Never trust a gok, since they just care about themselfs and noone else. A gok is also known for just "falling in love" with beautiful and very sexy girls. An ugly/fat girl doesn't exist in a gok's world. A gok doesn't know what love is, he just wants to get laid and then leave the girl to find another one to get laid.
