Nigerian Bifocals

The sexual act of dipping one's testicals into fecal matter and/or feces, and thus proceeding to gently plop one's testicals upon the eyes of his partner. SEE: ARABIAN GOGGLES

I went to a craigslist optometrist, Dr Puup Jarvison, and all I got was Nigerian Bifocals and pink eye.

Bilinear Bifocals

Optical powers on seeing variables or positions that aren't seen to the normal perspective.

I was driving down the road and looking at the clouds and was like wow, bilinear bifocals.
It's what happens when you eat too much mescaline.
