Slang for scabies. They're small mites that burrow into the skin and lay eggs. They cause intense itching and are passed through skin to skin contact or exposure to them in bedding or clothing. While not always passed via sexual intercourse they frequently are in teenagers and young adults.

Bobby: What the fuck is an STM?!
Jay: It's scabies. They're a STM (sexually transmitted mite). He supposedly got it from that broad he was humpin'.
Bobby: Wait. Isn't that what you just had?
Jay: I don't want to talk about it.
