After titty fucking your bitch, you cum on their chin. The skeet skeet beard makes him/her look similar to the "headmaster" of hogwarts, Albus Dumbledore.
Also commonly referred to as:
The Gandalf.
The Santa Clause.
Or my personal favorite: giving someone a "my grandpa."
After I gave my girlfriend a Dumbledore, I felt the need to slap her in the face with my wand.
