Dong a long sing a song 

When the male takes a whip while letting the female suck his dick, to add on vibration the girl starts singing so her mouth and tongue vibrates around the whole dick seemingly creating a vacuum of unholy vibrating pleasure, if the female stops singing the whip is used as a second method to make the female scream to which vibrates the throat which the males dick should be in.

Guy:"hey girl wanna do a dong a long sing a song?"

Girl:"sure baby im gonna fill u up with some justin beiber"

Guy:"you better not stop or i will whip you"

Girl:"mmmm kinky"

Powerpoint Sing-a-Long

Any powerpoint presentation in which the presenter reads from the slide verbatim without any side comments, observations or examples. Use of monotone voice usually goes with this.

I could hardly stay awake during that last presentation. What a powerpoint Sing-a-Long! On the plus side, he did a killer Ben Stein impersonation!

Dr Horrible's Sing-Along Blog 

The greatest thing Neil Patrick Harris has ever been in. It it a Musical Comedy, roughly 45 minutes long, about a city villian who wants to make it into the Evil League of Evil, defeat his Arch-Nemisis Captain Hammer (corporate tool), and impress the girl of his dreams. Has many hilarious quotes, and a large fanbase.

"Did you see Dr Horrible's Sing-Along Blog yet?'
"Naw, dude, I was too busy"
"*shoots kneecaps off of the other guy*"

Dr. Horrible's Sing-Along Blog 

A humorous web-based mini-movie musical starring Neil Patrick Harris and others.

Neil Patrick Harris plays the role typically seen as the bad guy (an evil genius) and fights Nathan Fillion, as Captain Hammer (the usual good guy), over a mutual love interest (Felicia Day, as Penny).

I just watched Dr. Horrible's Sing-Along Blog for the first time!
I'm buying the soundtrack.
:D

Hong Kong Sing Along 

The Hong Kong Sing Along is when a man is having sex with a woman, and as she is screaming in pleasure he mimics everything that she says(or screams ) in her own voice, thus, in essence, singing along with her.

Woman: Fuck me harder Johnny! Harder!

Guy: (In woman's voice) Fuck me harder Johnny! Harder!

Disinterested Observer: My girlfriend would kill me if I broke out into a Hong Kong Sing Along.
