fuck my shit up

To tell your Barber/Hair Stylist to give you a strange or messed up haircut.

Whenever something really turn you on, hooks you, intrigues or interests you, that thing "fucks your shit up." Only use for major things, not minor things; i.e., you wouldn't say "Cheetos fuck my shit up" unless they literally feel orgasmic in your mouth. And, yes, this idiom allows sarcasm. *Can be referred to as an acronym, FMSU.
