"That girl's so nasty, I bet she has a Crusty Trout"
Noun,. After having vigerous sexual intercourse the male ejaculates onto the hair of his partner and begins massaging his semen into her hair until it starts to become sticky he then fluffs the hair upward and outward repeatedly until it dries into a Rio Carnival style headdress. When done with love it can be very attractive, but if done with malice it is a tangled mess.
(1)"Jess, your hair is devine... who did it." "Thanks Jodie, Brad gave me a Crusty Rio!"
(2)"What happened to your head, did Jim give you a Crusty Rio?!?"
When a guy blows his load in a woman's vagina, doesn't wipe himself off, and then about 15 minutes later, when their mixed fluids have dried on his penis, forming a slight crust, he puts his now "crusty loaf" in her mouth.
