That feeling you get riiight when you're peaking the top of the "addy mountain". Not to be confused with "talk to the conductor" or "the train". This is the moment after you've taken you're so called ADD medicine that shit really starts to get done. Normally lasting (in a higher metabolism individual) no longer than 1-2 hours, give or take. At "the peak" one will generally find an insatiable need for nicotine of some sort and possible "jawing" may ensue.
Yo dawg, I just ripped about 40mg of addy and I'm on that jaaaaaaaack (That Jack).
