look up anything, like your first name:
1. gwean
verb: to rub or massage the penis "all up and down" someone's face in a non-aggressive, loving manner.

not to be confused with mushroom stamping.
I gweaned her so gently, we made love for the next three days.
2. Gwean
An adorable sound, like a "yay" that you'd often hear from a babycheek.
"Gwean Gwean!"
