What is Gicks?
1.
Someone who is not expressly one's girlfriend/boyfriend; however, they are still mutually exclusive. For instance, they will attend parties together and might hook up. People know that they are "off-limits" yet the gicks's are not literally going out.
Guy 1: *Ski-ooop*, that girl is pretty hot.
Guy 2: No man, didn't you know? She is Jeff's gicks - she is off-limits.
