Uboa
Uboa is a character in a 32-bit PC game called Yume Nikki. He/ it appears in a random event in which you turn the lights off in Poniko's house, causing Poniko's sprite to change into Uboa. In this event, the room is changed slightly, and a muted "aaaaaaaaaaaah" sound is heard. He is known for surprising players.

U-bend U-boat
A turd that is submerged in the U-bend of the toilet like the german submarines (U-boats) used to hide beneath the surface of the sea. 9 out of 10 U-bend U-boats are unflushable in the average toilet.
For fucks sake, that U-bend U-boat just won't flush! Pass me the bog brush Dave, it turd bustin' time!
