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!
