The following hip-hop related flicks have notable breast scenes, beginning with the biggest.
-I Got The Hook Up- is a bizarre throwback to old school black comedies like Cotton Comes To Harlem and Uptown Saturday Night. The scene in question is the very first shot. Under the credits plays a candid scene of street life in New Orleans (actually L.A.). When there, on the horizon is a mammoth breasted ghetto queen. It's unclear whether or not she even knows she's on camera. The closest thing to a candid huge sighting in mainstram film we'll ever get. There is also
a roomfull of big busted strippers hidden away in John Witherspoons hidden club.
-Class Act- Kid N Play's one non-House Party outing is corny but has 4 notable busts. The first is Kid's face first collision with the massive bust of the school administrator. Similar to the collision in Last Resort. The second belongs to Damita, a buxom main love interest she gets the most screen time. The third, biggest and best belongs to the uncredited woman in the blue dress from the club scene. She is unbelievably proportioned and filling out a blue spandex dress while Kid compares her to skiing the blue mountains of Switzerland. Also in the track and field scene keep an eye out for the busty latina extra who distracts Kid as he trip over a few hurdles.
-The Disorderlies- This Fat Boys vehicle has one cute comedic shot of Troy Beyer (Let's Talk About Sex) jogging on a treadmill then pans down to show her bobbling brests complete with Hanna-Barbera boing sfx.
Not huge but memorable. Possibly the ideal comedy boob gag.
No memorable breasts in Breakin 1 or 2, Beat Street, Juice, Krush Groove. Run-DMC Tougher than Leather has a topless bondage queen of average size. Khandi Alexander (News Radio) gets some topless action in CB4 (may be a double though).
