Same here. When I was in high school was when lezzing out was big, or getting there. The result was either a girl "dating" another girl they referred to as their "wife", but without any kissing, hugging, or anything beyond the kind of contact you'd see in friends.Reading this makes me really glad that I was in high school way before it became "hip" for kids to start trooning out.
Or you'd get a girl dating a guy and another girl (who was also a "wife"), but the difference here was that the "wife" would usually also have a boyfriend, and the two girls would openly cuck their boyfriends out in public. Typically by completely ignoring their boyfriends and having the kind of make out session you'd see in Girls Gone Wild or some other lesbian porn. The guys would just watch with an expression indicating they thought they were getting a private show, and she'll definitely pay attention to him later for sure.
Between this and the mental illness pissing contests ramping up at the same time, this was probably the major forerunner to the insanity we see today, just not as extreme.
