‘Celebratory’ Assembly

Definition---
An assembly with which to celebrate students ‘achievements’ such as birthdays. –held every Friday afternoon- similar to Mass, but is hosted by a manwho regards himself on par with God like stature, along with a long-haired Science co-ordinator, who, funnily enough, is a bitch; an assembly in which a regimented clap is allowed for a controlled burst of time.

Example---
HT: So let’s have on e round of a happy birthday rendition.
{Terrible piano playing ensues, coupled with the vocals to ‘Happy Birthday’ from children… followed by clapping.}
HT: Right! Nathan! You can go sit outside my office, there was no need for that extra-clap of an outburst.
Teacher: Once again, an excellent and most celebratory, ‘Celebratory’ Assembly

Reject this, I dare you.

I tried to add you to Urban Dictionary, but they reject inside jokes and definitions naming non-celebrities.

Celebration Cup 

In beer pong, a cup which each team fills 3/4 of the way up, and then proceeds to place anywhere in their own rack. The opponents turn around when the cup is being placed so that they do not know which cup to shoot at. When during the game either team proceeds to hit their opponents' celebration cup, the team whose cup it is gets to celebrate because, as a result, they get to drink extra! A loud celebration ensues, with all four players taking part--two of them because they hit a cup, and two because they get to enjoy more delicious Natty Light. It is also common courtesy to thank the opposing team for hitting your celebration cup.

"Dude look, they just hit the celebration cup!" (screams of joy ensue)

Celebration Parallax 

The phenomenon whereby the exact same set of facts is either celebrated or deplored depending solely on the political bias of the observer.

When a liberal writes that increased immigration is good because it leads to a liberal demographic shift, but then writes that conservatives decrying increased immigration are pushing "replacement theory," that's celebration parallax.

Slut celebrating

When you celebrate and encourage a woman’s sexual prowess rather than demeaning her for liking sexual intercourse

Person 1: Abbi loves sleeping with professors on the first date.

Person 2: Why are you putting her down? You wouldn’t if she was a man

Person 1: Oh no you didn’t get it! I don’t have an issue with it, I’m slut celebrating her! She should do it more often.

celebritney 

The term used to describe a "celebrity" who is famous primarily for bad behavior (due to either being completely devoid of talent or having their work overshadowed by their antics).

Tiger Woods co-cheater Rachel Uchitel seems to be doing everything humanly possible to prolong her celebritney status. (Look for her upcoming cover single "Me and Bombshell McGee" to drop any day now.)
