"All right nerds, lets go with -" Roll credits

The end of Pitch Perfect had Dick and Wally jumping up and down from sugar-fueled excitement, hooting and hollering, shouting 'THAT WAS AWESOME!' and 'PLAY IT AGAIN!' After the third replay, Wally exclaimed,

"We need to do a riff off!", which Dick completely agreed on. They were at the Cave, with the only other people around being Superboy, who was shut in his room doing whatever Superboy's do, and Aqualad, who had retired to his room when they started the movie in the first place.

Dick suddenly began a stomp stomp clap rhythm, then began singing quite loudly and excitedly,

"Buddy you're a boy make a big noise
Playin' in the street gonna be a big man some day
You got mud on yo' face
You big disgrace
Kickin' your can all over the place

We will, we will, rock you
We will, we will, rock you! - ", he practically yelled, getting right in Wally's face, challenging him to do better, to which Wally interrupted with

" - you from the beast about to strike,
You know it's thriller, thriller night!
You're fighting for your life inside a killer, thriller tonight - " then Dick smirked and took over with

" - tonight, we are young!
So let's set the world on fiiiiire!
We can burn briiiiighter than the suuuuun
Toniiiiight
We are young
So let's set the world -" but Wally cut him off with an extremely off key version of

"Wooorld! A new fantastic point of view
No one to tell us no, or where to go - ", but as he was about to screech another line, Dick bounced up to him and countered that with,

" - go,
Where did you come from Cotton-Eye Joe
If it hadn't been for Cotton-Eye Joe
I'd been married long time ago
Where did you come - " then quicker than he thought Wally could come up with anything, the redhead sang,

" - Come and get it! Na na na na
When you're ready come and get it - " and Dick took over again - the competitiveness was starting to get out of hand, the intensity present in the room was extreme. He mouthed off,

" it feels so empty without me!
Now this looks like a job for me so everybody just follow me
'Cause we need a little controversy
Cause it feels so empty without me - "

" - me, got an angel on my shoulder and Mephistopheles! My momma raised me good, my momma raised my riiight - "

" - right, where you want me! Can't explain it, how you swept me off my feet, unexpectedly!" Dick threw up his arms in a 'come at be bro' gesture, continuing the song," In slow motion, my - " but he was cut off again by Wally, who to the 13 year old's dilemma, chose a song he wasn't well versed in.

"my head,
Glitter all over the room
Pink flamingos in the pool
I smell like a minibar
DJ's passed out in the yard
Bobby's on the barbeque"...

For two hours neither would admit defeat; this was war. It was only brought to a stop when Superboy yelled quite irritably for the two of them to "shut up" cause "You're driving me nuts."

When they finally settled down, both felt maybe a tiny bit foolish for letting it get carried away like it did, but no matter; it was soon forgotten.

However, quite a few members of the Justice League had a heck of a fun time watching it back on the security cameras later on...
