Facebook assumption

A very common mistake among gossipy and gullible teens. Its just making assumptions based on snooping people's facebooks, Such as assuming a guy wants to be with a girl if they have a back and forth wall post exchange. Its easy to keep up with information like this because news feeds inform you about everyone's activities and posts. Can also be Myspace assumptions.

Scenario 1: Teen 1: Dude, I think Karl likes Marissa, he posted almost 10 comments on her wall

Wiser Teen 2: Naw man, don't be making facebook assumptions. Facebook posts do not an attraction make.

Scenario 2: Dude 1: I'm so juiced, that cute freshman just sent me 5 messages, I'm definitely asking her out now.

Dude 2: Man, she hasn't even said hi to you in person yet. You're making a facebook assumption. I expected more of you.

Assumption English School

Known for having the reputation of a gangster school, it has come a long way. Don’t get me wrong, wannabe cool kids still exist and can be found shouting for attention in the canteen.
Basketball is Assumptions’ pride and glory.
Assumption English upholds very “reasonable” rules such as banning all sweaters and jackets in the school premise.
AssumptionKnights can mostly be found lurking around Hillion after school or smoking behind the bus stop.

WAH! Look at those kids smoking in uniform, they must be from Assumption English School.

The aTRUMPinator

Very similar to The Assassinator -- some very intelligent person (***NOT*** a true-blue total asshaberdasher!) who assassinates President-Elect Donald Trump.

The aTRUMPinator was on the prowl for Trump not far from the Trump Tower in New York (which was firebombed the other day) looking to assassinate the asshole before he took the Oath of Office.

Assumption Song

An assumption song is a song with the intention of making you think it is dirty when really it doesn't say anything dirty by changing the rhyme.

"...Refuse and litter from yesterday's hunt, when the girl in the meadow was rubbing her... eyes at the fellow"

Everyone knows it is dirty though. It's no secret.

"Hay, Can I sing the assumption song for you"

"Sure!"

"*sings*"

"Eww gross *Throws pie in face*"
