A crushtache is an individual you have a crush on simply because of their mustache. You may actually like the person as well, but most often you don't even know them, they just have a really good mustache.
1. "I saw this guy riding a vintage schwinn with a great mustache. Total crushtache."
2. "Well I had a total crushtache but he turned out to be a jerk."
The RustyCrustacean is a sexual act where; a female lays on her back and her partner puts their thumb inside the vagina and four remaining fingers inside the anus of the female. Then, the partner squeezes their fingers together (reenacting the movement a crustacean's claws make when closing) causing fluctuation of the vaginal and anal region of the female. Maximum pleasure is promised if performed correctly.
