In broadcasting or sound engineering, redlining is when the levels are set too high and the lines on the screen/board are in the red instead of the more desired orange or yellow. Leaving levels at this high level may cause your audio to sound distorted and unpleasant.
Dude, your levels are up too high, you're redlining!
A set amount of RPMs which your engine can put out before you pretty much blow it up. This is usually where your numbers on your tachometer start turning red, just be sure to keep it out of the red or else $$$$ will be needed. For instance, the redline on my 95 Jeep Grandcherokee is 5,300 RPMS that is exactly where they start turning red, some cars have a rev limiter on them, so due to my rev limiter the engine will not go past 5,300rpms and the engine starts "bouncing" meaning the needle will do the same. I advise you not to try this.
Dude your not supposed to shift while ur racing till you redline it

The best energy drink ever. It will (with 8 oz, no less) get you to the most energetic you've ever been, and you'll stay there longer.
Shake well prior to use. Always begin use with 1/2 can of REDLINE daily to assess tolerance. Never exceed more than two cans daily or more than one can in a four-hour period. Do not consume REDLINE on an empty stomach. Consuming REDLINE on an empty stomach may cause nauseousness.
That warning is serious. The drink is serious. It's hands down the best.
I once drank a redline before a dance, and not only stayed at my peak the whole dance, but stayed there until the next morning.
Don't drink these on an empty stomach- you'll almost guarenteedly throw up.

To do something that scores major disapproval and/or anger. To many motor-heads, this term can be used perfectly, as it correlates with "redlining" on a car motor with RPMs.
"Dude, you slept with my sister. That's such a fucking redline."
"You're redlining right now and it's really pissing me off. Cut it out."
