A phrase used mainly by weed smokers.  It refers to taking a break from smoking, or smoking less often, in an attempt to lower your tolerance to THC, and thus gain a better high each time you do smoke.
Yo man, I've been blazing up every day for a month, and it's just not the same anymore.  I need to take a tolerance break.
