Underpants Gnomes

The Underpants Gnomes are mystical creatures that bring you back all of your missing nugs at the most opportune times. Whether you lost your frosty green nuggets during a fumble in the car, or you lost your whole sack during a drunken rampage, the Gnomes are sure to bring back what is rightfully yours in due time. If they happen to give your pot to someone else, do not worry, for the Gnomes are fair and will reimburse you at a later time.
They dwell anywhere that you may have been smoking pot, but these honored creatures never show themselves. Regardless, they must be thanked and honored when they present gifts.

"I dropped a couple nugs on the ground right here and they just vanished! WTF!"
"Ah bummer bro, it was probably the Underpants Gnomes."

"Fuck yeah, check this loud loud I just found under my seat! Must've been the Gnomes."

chocolate undercarriage

The covering of shit on the bottom of a man's balls, when a girl shits while having sex.

She was so excited to have sex with him, she forgot to use the bathroom, and gave him a chocolate undercarriage.

underpad

The lowest inhabitable level of a multi-story dwelling; often used as a "hang-out space" or "chill-zone" seperate from the daily living space.

I'm too high to ring the doorbell of your parent's house, so I'll meet you at the back door of the underpad.
