Gay Line 

Whilst a healthy discussion about penises is permissible, if there is a prolonged fixation on one’s own or others penises, then that person will slowly approach the gay line. If someone crosses the gay line, then they will become irrefutably gay forever.

You’re getting dangerously close to the gay line mate

thin gay line

The midpoint line on the Tate scale which separates flirting with homosexuality from actual, gay sexual contact.

The Tate Scale, named after Internet celebrity Andrew Tate, is a logarithmic scale from 0-1 which measures the gradient of homosexuality in a person or activity.

Any measurement on the Tate Scale approaching 0.5 is, definitionally, the Thin Gay Line.

"My friend wanted me to go rollerblading with him on the beach, but that's just too close to the thin gay line for me."
