When a man hunches over a woman and eats her out, though from behind. That is, she's lying on her stomach and he's crouched over her back, pulling her legs up, naturally, to eat her out more easily. She may or may not be wearing a Mexican wrestling mask while he does this.

Get the boston crabmug. Penthouse crabs are lice. They get their name from crabs, which are mainly found in the pubic region, who migrate, or "move on up" to the head, the "penthouse" of the body.
Did you see Brittney Spears scratching her head on Dateline the other night? It looked like she definately got a case of the penthouse crabs.

When someone licks in circles around your butthole then sticks their tongue inside while while stroking your cock or fingering your pussy.

Get the crab mcgrawlmug. The act of trying to come up by stepping on others, thus keeping them down. Like a bunch of crabs in a boiling pot of water trying to escape. If they helped each other get out, most would, instead they all die. This is analogous to the economy in California. Everyone wants to get rich, raising their prices for goods and services. Effectively everyone loses.
The price to remodel a kitchen in California is 3x higher than in Texas. Its the same raw materials, why? It's the contractors and their suppliers crab potting the consumers. It's ok, I'm a car mechanic, wait until their trucks break down i'll return the favor.
