When a guy climbs up on the fence in his neighbors
yard and
wiggles his willy while the neighbors watch from a
window.
Can be used as a verb- wabbernugging
girl: "daddy what is this man doing out on our fence?"
Dad: "oh don't worry about that
Sophie. he is just wabbernugging! "
I just saw an old naked man climbing on the fence in my
yard and wabbernugging all over!
"damn that I really like how he wabbernuggs on my fence" - an old lady looking from a window
