oh wow tits that is so naughty I'm gonna call GWR. Just Kidding. You're a fucking dumb ass I bet you don't know good sex if it came up to you dick. Stay at home weakling.
I call them breasts in 'formal' contexts, I call them tits, informally, and my own I refer to as 'the boys'
generally speaking or whatever i call them my boobs, if i'm in a sexual situation or talking about sex i call them my tits, or if i'm drunk haha.
