In the video, Ton Loc demystifies the "funky cold medina" when he points to a bottle of Absolut Vodka. Though the concept of a "funky cold medina" is generally a drink - not just pure vodka. It's made by pouring one oz respectively of Absolut Vodka, Southern Comfort and Blue Curaçao over ice and topped of with cranberry juice.
"Funky Cold Medina" was also re-recorded in 2000, this time Ton Loc teamed up with ZZ Brothers.
"put a little medina in youre glass and the chicks will come real quick"
Aperently for one it is an alcoholic drink made by pouring 1 oz. Absolut Vodka, 1 oz. Southern Comfort, and 1 oz. Blue Curaçao and cranberry juice on top of ice.
The other found online is it is some sort of disease which origionated in the arabian city of Medina in north africa, which I actually found on this web page (look down).
The last one, which I derived myself was that it is a non-alcoholic date-rape drug which Tone LOC talks about using in his song.
Then he licked his bowl and he looked at me
And did the Wild Thing on my leg"
"I went up to this girl, she said, "Hi, my name is Sheena"
I thought she'd be good to go with a little Funky cold Medina
She said, "I'd like a drink, " I said OK, I'd go get it
Then a couple of sips, she sold licked her lips
And I knew that she was with it"
So I gave him a blowjob and then when it was my turn he just pulled up his pants, laughed at me, winked and said
Funky cold medina"
