When a broad's tiddies are bouncing around like they're Super fuckin' Mario. Ideally she'll be yelling, "Wahoo! Yippee! Wahaa!" in a Mario voice the whole time.
I got them big-titted broads jumping on a big trampoline, yelling and laughing and having a good ol' time. It's a good, old-fashioned Super Mario THOTyssey in my back yard.
