The sexual act of spitting/ejaculating into your partner's mouth. Then, the partner with the spit/semen, spits it down the first spitter's butthole.
I just ate hot cheetos, so I had a lot of spit in my mouth, so I asked my bitch if it was cool if I spit it in her mouth cuz she was thirsty. I was astonished when she asked if she could do some Repainting the Basement, but I obliged anyway, and it was worth it.
Masturbation. Derived from the Family Guy episode where Brian was married to Lois. When she would turn him on and not have sex with him. He would say Im going to the basement
So what are you doing this Weekend
Well Im going to the strip club with my friends then going to the basement when i get home.
