He props the woman up on his cock while standing and slams her into the wall while he vigorously penetrates her like a jackhammer, causing her to latch on, wrap her legs around him and dig in her nails while moaning in both delight and pain. They leave deep indentations and outright holes in the wall from their lovemaking, and Goofy has to hide them with artwork until he can find the time between fucking bitches to get the right materials to fix the wall.
That's what he meant by that.
