First of all: Super Straight and Ultra Straight are to seperate things ... Super Straight about your preference of not wanting to be with a trans person, while Ultra Straight meaning that your only into the opposite sex, in their gay form ... For example:

If a Ultra Straight man wanted to be with a women, he would be with a lesbian, because straight women likes dick, and for you prefering a women who likes dick, is gay.

the insult worse than
ur brother a mother
ur granny tranny
ur sister mister
ur mom gay
ur dad lesbian
ur grandpap a trap
ur family transgender
ur country bisexual

The most catastrophic and devastating insult available. Everytime a mortal mentions this forbidden word, the void approaches earth with greater magnitude

The stupidest thing you can ever say, stupider than trying to drift a train.

When you pour/grab 5 and only 5 Skittles candies from their bag and get one of each color : green, red, orange purple, yellow. References the card game hand 'straight'(i.e., a 5 card hand that has 5 cards that are sequential in number/face value)

All knowing of the Straight kind, all straight, only straight, nothing else.
