When a man or Maan recieves fellatio from his partner while playing a video game. In order for this act to be deemed a true gamekin, the reciepent must continue playing the video game, even though he is typically quite distracted. Derived from the terms game and blumpkin.
While I was owning fools in Call of Duty 4 last night, the old lady gave me a killer gamekin.
Gamuchirai is a very shy girl, cute and funny but sometimes may act out of character. Everyone enjoys her company. She is quiet, smart and have a body most girls would kill to have. Gamuchirai has a low self-esteem and likes to think less of herself. Have an enticing voice, can go for hours listening to it. Though she might appear to be funny and tolerant, you would not want to cross her. But all in all she is an amazing person and life would be so much boring without her.
man, did you see that girl??
yeah fam... she a total Gamuchirai
