Super-heterosexuality 

Super-heterosexuality is the romantic attraction, sexual attraction or sexual behavior between persons of the opposite cisgender and excluding all non-cisgendered individuals. This means that super-heterosexual individuals exclude 1) trans-genders, 2) trans-sexuals, 3) non-binary individuals, and 4) agender individuals from their pool for dating, marriage, and sex.
Super-heterosexuality is often commonly known as "super-straight."

Super-heterosexuality Example 1:
Person 1: Hey, Lakesha is interested in dating you. Do you want to date her?
Person 2: No. Lakesha is a trans-gender and non-binary. Sometimes she also identifies as a penguin on Mondays. I am not interested. I am only interested in opposite cisgender individuals.

forced heterosexuality 

When two characters of the opposite gender don't really go together at all but the writer throws them together just because they're male and female.

"Damn I can't believe the writers of Riverdale put Jughead and Betty together. That's literally the definition of forced heterosexuality. "

Heterosexual™

When a person is so undeniably straight that it either

1. Makes others uncomfortable or
2. Makes you want to pimp slap them
Unlike heterosexual, which is simply the attraction to the opposite sex.
Heterosexual™ is most likely used in texts or while posting and not in speech, though a minority does say "Heterosexual tm" while speaking

"Your hair looks really good, bro! No homo though." "Dude, dont be so Heterosexual™"
