To be fucked up the ass for so long, that the mucus in your ass starts to foam and leak out. See also anal fluid
Jane - "Oh baby, your cock is so tight in my ass, I think I could fucking explode"
Bill - "It looks so good too, baby. Your foaming at the ass!"

Get the foaming at the ass mug.
The usually odourless fluid/mucus that leaks out of your ass after pro-longed anal stimulation. It isn't semen, but rather your own body's colon lubrication that has pooled up behind your anus expecting more rectal stimulation. Usually comes out in one large blob like a loogy. Beware of farting while this is inside of you.
Joan - "Boy, after Max reamed me for hours last night, I've done nothing but fart anal fluid."
Sally - "I know what you mean. For hours after a really long anal session with Joe I feel like I'm foaming at the ass!"
