Get the blow you in mug.
while someone is doing ecstasy, people will get nasal vaporub things and blow it on your face and in your eyes, causing the individual to become refreshed, and energized to continue dancing and feeling good. People also sniff vaporub by sticking it up their nostrils or getting a tub of it and spreading it on a surgical mask.
