An acronym that stands for "Tiny Body Huge Cock". Used to describe a dude with a small/short frame that has (seemingly) disproportionately huge cock that is close to if not outright the size of his torso.
Oh my god Sarah, I took this one short, cute guy from the club home with me to have a one-night stand, and let me tell you that you would not believe the absolute size of his member! The dude was a total TBHC, I'm aching from the experience LOL!
12 step recovery jargon referring to someone new who talks about how great life is, now that they'resober. Usually meaning that the person is out of touch with reality.
The new guy seems pretty happy for a dude who has no job, no money and no family. He must be on a pink cloud.
