look up any word, like the eiffel tower:
when one takes more than the recommended dosage of Advil either to prolong the effects, or because they are pissed off, and just want a drug but are too afraid to get a real one.

"no, I just took some Madvil"
"what does that mean?"
"look it up on urbandictionary!"
