believe it!

The most horrid, terifying term in the history of anime dubs.
Derrived from dattebayo by a sick, twisted dub comapny in order to subject children to mind control via lame sayings.

In short: "Dattebayo" is a cool way to end a sentance. "Believe it" is not.

"I'm Naruto uzumaki, and I'm gonna become the best Hokage ever, believe it!"
VS.
"I WILL be Hokage, just you wait! Dattebayo!"

make beliefs 

Various pretensions and desperate believings manufactured, brainwashed and clung to in order to compensate for and quell the fear of THE UNKNOWN. Usually take the form of religions and cults.

1. Omar had been brainwashed into the way of the crescent moon prophet from an early age and was firmly entrenched in his make beliefs.

2. When Donna hit bottom in Key West; her anxiety and desperation led her to Jesus and a ready made group of make beliefs.

3. Even though raised Roman Catholic, Madonna gravitated to Caballa and other Judaic nuances to fill a void in her system of make beliefs.

Believedat

Arguably originated in New Orleans, LA though it is widespread throughout the southern region of the United States. Made popular nationwide by Dwayne Michael Carter more commonly known as Lil' Wayne, "Believedat" (pronounced ba-lee-dah) is a combination of the words "believe" & "that". It is used to reinforce a previously made point or objective.

I don't care what day it falls on, when its my birthday I'm going out, popping bottles, dancing my ass off and bringing someone home with me...believedat.
