ululation 

A loud call one makes by producing a sort of howling noise from their lips, and then repeatedly tapping their hand over their mouth to make a sort of undulating noise that travels far and wide.

The children made a loud ululation when pretending to be Indians.

thumbs upflation 

Repeatedly going back to a word you defined on Urban Dictionary and clicking the thumbs up icon to inflate the popularity of your word. Like shaking it out at a urinal after a nice piss, you're entitled to one or two shakes, but not 45.

I define slut slam on Urban Dictionary. I think it is hilarious, but it gets no traffic or a few thumbs down, so I keep coming back to UD and give my word some thumbs upflation.

premature strike-ulation 

When you are bowling and you THINK you bowled a strike, so you start celebrating by doing your little dance, but then you turn around to notice you still have pins standing.

Man, jon totally looked like an IDIOT when he thought he got that strike. He did a little breakdace move, while everyone was laughing and pointing at the lanes, he finally turuned around and realized it wasnt a strike. CLASSIC case of premature strike-ulation

uvulation 

1. The act of snogging/sucking face so industriously that one runs the very real risk of interfering with the snoggee's uvula - the bit of the soft palate that hangs down at the back of the mouth. Often associated with spin the bottle and other such pursuits. Anywhere teenagers or drunken students are present should be considered an "at risk" zone.

2. Can also be used as a verb: to uvulate.

1. Sober student: "That is some serious uvulation going on over there. That guy's, like, performing major surgery on that chick's throat."
Half-cut student: "Yeah, sick dude! On the other hand, once I've seen this pitcher away I will find it strangely appealing to engage in such practices."

2. Horrified bystander 1: "I can't believe it! Uvulating in public before 2 in the afternoon!"
Horrified bystander 2: "Oh! The youth of today have far too much saliva and absolutely no discretion!"
