Velky Bobor 

Slovak for a sex act in which a man receives a reach-around while his male counterpart blows sweet nothings into his dirty asshole. This is familiar to most Americans as "The Rusty Trombone"

Did you hear Cliff walked in on Dan giving the ole Velky Bobor out to the local trick-or-treaters the other night?

I don't think he'll ever be the same...
