This popular studying aid originated in Philadelphia and consists of taking an adderall and consuming an energy drink simultaneously to pull an all nighter studying for an exam. You can also take the adderall and consume the energy drink a few hours later for the same effective boost. It is most commonly practiced during finals week at universities across America.
Overheard at a college library:
"Yo man, I did a Philly Thunder last night and aced the exam. That shit was wild"

"Yea that Philly Thunder will keep you buzzin for hours"
