mong out
n.— «At thirteen pound a tenth I don’t see it as a bag of weed, I see it as a #13 E that’s gonna last me ten hours when I hammer the whole bag. You can’t tan black or hash like that ’cause you’d just completely mong out.» —“Super Grass (Part 2 of 3)” by Mandi James UK Mixmag Oct., 1993. (source: Double-Tongued Dictionary)
