A Polish date is when you meet a trash slut online that you want to fuck cause you're horny, but you don't want other people to know about it, because she's so gross. You roll over to her house (has to be her house) with a bottle of cheap vodka, so that you barely even remember the whole thing, except getting your nut off.
Hey did you hear that Jim Wisniewski took your sister out for a polish date?
A date in which a girl goes out with a Polish-American guy with a muscular body and a huge dick.
Most girls who know what's good for them can't wait for a polish date.
