Getting "Backdrip" occurs after snorting cocaine, when spit and coke is stuck in your throat after a line, usually a few minutes later. It has a pungent hairspray taste and may occur a number of times. However if this does happen don't spit it out becuase you could acheive a larger high if the "Backdrip" is swallowed.
"UHHH, i got the dirtiest backdrip!"
