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.
