padikake
When you slap someone's butt while you're licking their butt hole at the same time, like you're trying to make them feel both good and gross!
I did a padikake to my brother and he ran out of the room screaming!
My friend did a padikake to me during lunch and I spilled my drink.
I did a padikake to my crush and now they won't look me in the eye.
