flip up 

To have an erection and attempt to disguise it by flipping your penis upwards -- so it is held between you underwear/pants and you waistline.

My teacher asked me to stand up in class, I had a huge boner so I needed to flip up quickly before I stood.

flip-up 

A lesser hard alternative for "fucked up" but with same meaning. It means you failed to do something, or didn't suceed in doing it.

I failed in making a good conversation with her! I'm a failure! I flip-up every time!

flip up friday

A junior high hallway activity where girls were subject to having their skirts lifted from behind in order to see their pantys. Giggling and running to the safety of the girl’s bathroom was the usual response. Occasionally she might turn and glare. Many wore shorts under their skirts to thwart the boys. This was common in the Tacoma WA are in the late 1950s and early 1960s.

Jane: Remember, tomorrow is flip up Friday.

Jill: whoa, I better wear pants!
