Get the butt custard mug.
1. Dried poop particles stuck to the anal hair. Similar to dingle berries but not quite as chunky, more of a nice crunchy glaze.

2. Also Known as an E-Cig flavor joke to mess with people with its rather repulsing sound. The flavor doesn't taste like ass, its actually composed of CRUNCHY cinnamon, BUTTerscotch, and vanilla CUSTARD.
1. "Man I've been walking all funny cause the dump I took this morning left me with some crunch butt custard"
2. "DUDE IS THAT A VAPE!?!? WHAT FLAVOR???" "Crunchy Butt Custard"
