Slang for "in the closet". Meaning that someone is L/G/B/T/etc. (lesbian, gay, bisexual or pansexual, transgender, etc.) but hasn't made it public yet.
Person 1; Oh my God, did you hear Justin Bieber's new song? He's totally itc.
Person 2; No way he's gay -- but Tom Cruise totally sets my gaydar off.
