pronounced like kicks with a "G". It stands for Girl I am Kind of Seeing or Guy I am Kind of Seeing. Refers to anyone that you wouldn't consider a girl/boyfriend or even someone that you are dating. Basically you hang out from time to time and probably screw around a little bit.
No, she is not my girlfriend, she is my G.I.K.S.
