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.
Holy shit did you see that guy shoot the old couple the peek-a-boo moon when they walked by.
To observe the new moon is a code word used in the workplace. It means to descend on the New Moon Tavern in Leadenhall Market, London and indulge in a Cold Beverage whilst gazing up at the New Moon sign above the bar...
Hey, Would you like to join me in a spot of moon gazing? Yeah why not, I will be happy to observe the new moon this evening.....
