The Butt Gorilla is a nocturnal primate who climbs into young boy's windows at nite, and commences to have butt-secks with them. His voice sounds eerily like...your Dad's.
Boy: "Dad, I had a nightmare that a man in a gorilla suit humped my butt. And it really hurts!"

Dad (With a twinkle in his eye): "Oh, that ol Butt Gorilla must've visited you last night! Now hurry up and put this dress on!"

Get the Butt Gorilla mug.
an expression to be used when something just, like, totally sucks big time...
saw my ex-GF sipping an iced Cinnamon Dolce Latte at the mall today with my replacement, Brad, that total jerk-off... she was smiling and laughing and staring deeply into his eyes... just like she used to do with me... and then I realized that I was still so totally in love with her... talk about visiting heartbreak hotel! I nearly burst into tears in the flipping mall...

that's too bad, bro... I feel your pain, I truly do. we've all been there. seeing an ex you still love with a new guy always totally sucks gorilla butt...
