Collegiate A Cappella 

Music done by college students involving only voices and no instruments. Usually sounds stupid and worse than the original hits because the performers are drunk and care more about getting laid. There are some good groups, but mostly just a soloist sucking and the rest of the group going "doo-doo."

Kayne West: Yo Off the Beat, I'm really happy for you guys, and I'm gonna let you finish, but the original artists had better versions of the songs you covered.

Oscar Wilde: Collegiate A Cappella? Sounds like getting dildo up my ass.

caellum 

Caellum is a tall boi who is really cute. He gives the best hugs and is caring. He has a great sense of humour and super sarcastic but not enough to be rude. He has an awesome music taste and has really good production skills. He is very loyal and cares for his friends a lot. He also lowkey has a soft boi side. If you ever meet a Caellum then keep him because he’ll make your life so much fun.

A cappella 

"A capella" definition is wrong. Not usually used by rappers, but rather by people that actually...sing (and sing well) without instrumental accompaniment. Please see

http://www.singers.com/a-cappella.html

...for more enlightenment on what a cappella is.

"Hey guys, let's sing real a cappella, with no instrumental accompaniment. And better yet, let's actually sing and use musical notes in our music and not chant simple rhymes and curse words in a monotone like the music artist b rabbit does in 8 Mile!"

"Sounds great! Wait, b rabbit is a music artist? Since when?"
