Peek-a-boo Moon

The act of placing ones ass cheeks against a glass door, pushing a turd out just enough to kiss the glass and pulling it back in. Usually performed at bachelor parties, random hotel room where pool guests can see etc.

boos reacts only

In the context of the new Facebook react icons, there is one with an angry face. When someone posts a dank meme to offend a group of people, he will type "Boos reacts only" so everyone will react angry instead of liking the meme.
"Boos" is the Dutch word for angry and is pronounced as "boas".

Person 1: *post dank meme about ethnic minority group and asks for boos reacts only*
Person 2: *reacts boos*
