2. roffle
A rare but fun sexual favor in which one person sits on a waffle iron (on or off depending on preference) long enough to get waffle marks on their ass cheeks. After this anywhere from one to five guys beat off on the person's "waffle ass", making what looks like an ass waffle with jizz syrup. Hence, the roffle.
Matt is happy because his girlfriend's flabby ass is perfect for the roffle.
