When one man places his penis in another mans ass crack
Let’s grout the tub tonight after the kids are asleep.
The act of having a degenerate female lie naked on a cement floor (usually garage or basement) while pressing her breasts together. One or multiple men then proceed to squat-shuffle over her while defecating. The bead of feces is implied to be the "grout" and the breasts symbolize tile or other masonry medium to which the grout is binding.
"Hey Dandelion, you coming over later?" "Nah, Mav. I'm gonna help some friends with something." "Oh, what?" "Laying grout." "Oh. Ok. I love you." "K. Bye." "I said I love you..." "Yea. Thank you. Bye."
