The lense

When you cum in a woman's eye and spit on it at the same time and acts as an eye lense and her vision becomes blurry so you proceed to put contact lenses above the lens layer.

Connor: Guess what dude! Rebecca let me do the lense on her

fatboy lenses

When you look back on an old crush, and realize that they were never attractive at all... you were just looking at them through sad, desperate "fatboy lenses".

It's like having beer goggles while being sober.

"Oh man, I ran into Jess the other day. She's so queer looking. I must have been looking at her through my fatboy lenses back at school"

Gucci lenses

Everything is fine. Synonym to Good or nice or sweet

Typically used as a response to a statement or incident. Generally as a way to express that everything is ok.
"Hey Jesus someone hit your truck??"

"Yeah but it's didn't even get a dent. Her car got damaged but she rear ended me. We're Gucci lenses"
