d.u.b.s.
D. u. b. s. is when you hide your hard-on with your belt or pants. It’s like a guy’s way of saying, I’m not getting a boner, I’m just doing math.
He did D. u. b. s. and looked like he was doing math.
I did D. u. b. s. and my head peeked out when I raised my arms.
He did D. u. b. s. so good, I believed him.
