I get my kicks above the waistline, sunshine
This is a phrase that British actor/singer Murray Head says when he sees an array of nude Thai stripper girls in the video for the 1985 hit "One Night in Bangkok". That song is featured in the Cold War-themed romantic adventure musical "Chess", which was written by the men of ABBA and appeared on Broadway in 1988.
Rocky, Freddy and Frankie are watching cable TV in their dorm room. The 1983 movie "Class" is being shown on HBO. It stars Jacqueline Bisset as a Mrs. Robinson type. You get the idea. After this preppy-ass boarding school kid meets her in a bar they are later in a shopping mall, in an elevator all by themselves and they kanoodle and he goes down on her and there is some noise being made. Frankie is disgusted by what he sees. He says strongly "I get my kicks above the waistline, sunshine!"
