speedballing refers to mixing herion and cocaine. both substances can be mixed together and snorted. or injected if you're extremely dumb. apparently it gives the feeling of falling down an escalator. it confuses the heart, because herion is a "downer" and cocaine is an "upper." so herion slows the heart down while cocaine speeds it up. its an easy way to have a heart attack if you aren't careful. yet to be experinced haha.

last night, i decided to try speedballing dude. it was fuckin ridiculous; i didn't even know what was going on.

genetic speedballing

The concoction of DNA that results in superior intelligence with a lack of common sense.

The guy who runs the ElectroBOOM YouTube channel is clearly a result of genetic speedballing.

speedballin out of control 

To do exorbitant amounts of dope (Heroin and Methamphetamine). Usually within the confines of one evening at the trap. Often accompanied by drug buddies, assorted paraphernalia, and no regard for any type of human reason.

"Yo did you see Jess at the trap last night? That bitch was speedballin out of control!!"
"Yeah that bitch ain't human!!"

"She just likes to play 'let's see how high we can get without needing defibrillator' crazy bitch!"
