A brown waldo is a bowel movement left in a strategic location that makes it hard to find. The more specific davenport (popularized by pro football player Najeh Davenport) would qualify, but a brown waldo may be dropped anywhere - not just in a closet hamper. You'll smell it before you see it!
This Christmas party sucks - I'm gonna go leave a brown waldo in their guest room.

Dude ... where's the brown waldo? I can totally smell it!

When you shit in a girl’s eyelids and then eat her out while she tries to play where’s Waldo.
Customer: “Hey, can I buy this book of Where’s Waldo?”

Cashier: “aren’t you a little old for that?”
Customer: “I’m going to give my girl a brown Waldo later.”
