The excess build up of ass cheese, vaginal discharge and sweat on that of a woman’s supposed “sexy” thong. This is do to the neglect of a daily shower and/or a fresh pair of panties. It will often resemble the color and texture of dried baby vomit.
Mom - (to daughter) Go get your sisters laundry and clean them please.
Daughter - Ewww!!! Mom!!! Come look at her crusty thong. It's the most revolting thing I have ever seen.
Mom - Dear lord, mother of holey Jesus, what in the hell is that!?
Daughter - Its her thong, I think. Im not touching it, you touch it.
Mom - There is no way I am touching that disgusting thing; besides, you found it first.
Daughter - No! I might catch something and OH MY FUCKING GOD!! I think it just moved.

Get the Crusty Thongmug. by brahm2 September 28, 2003
Get the butt crustiesmug. It is a product of the sexual act of a man performing anal sex on a woman while squatting over a bucket. Right as the man is cumming into her anus she proceeds to deficate and urinate into the bucket as the semen is forced out by her feces. The mixture is left to ferment for 6-8 days. It is then added to baking mix and made into cupcakes. These are then sold at a local church bake sale under the title of "Crusty Mexican".

Get the Crusty Mexicanmug. A surprise sex act where, while having sex with a woman on the beach, the man pulls out, sticks his penis in the sand, and quickly shoves it back in.
I fucked my girlfriend on the beach the other day. She's been such a bitch lately I was tempted to give her a crusty corndog.

Get the the crusty walrusmug. A guy does a girl up the butt and cums around her asshole. He thens motor-boats the girls asshole after she takes a shit. Cleaning up all the crusty poop and cum that is left there.
My friend kim, took a shit in the morning. Her boyfriend, dupree, came over and did her up the butt and jizzed around her asshole. After he stuck his tongue out and and cleaned up all the pooop and cum that was in between her cheeks. While this was happening her friend McCabe walked in and dupree spit out a crusty doodie in McCabe's eye. The girl kim then screamed out "Crusty McCame!"
