Oh My God (feat. Peaches) Lyrics

I've always heard the line in Peaches' end rap as "you make a drop in the cotton", as in you make my panties wet... I can hear nothing else there, but every lyrics site I can find gives either this version or even "you make it drop and get on 'em". Am I crazy? Can anyone defend "you make a drop and then caught 'em"? What would it mean?
