The belief that in a relationship, you'll never get 100% of what you want, so at most you get 80%. But some other person may come along and have that missing 20% you don't have. Some folks fall for the 20% just to realize they should've stayed for their original 80%. C/O Tyler Perry's "Why Did I Get Married?"
"Damn, my co-worker is so HOT and incredibly funny!"
"Think about the 80/20 rule, Becky. Think about it."

"Dawg! She is baaaad...34/22/36. Damn i would so hit that..."
"Whoa man; 80/20 rule dawg. Lisa is a good wife..."

A simple diet plan of eating only 80% of healthy foods and 20% of unhealthy foods.
Eversince a coworker told me about the 80/20 diet I now only eat garden salads and fresh fruits during the week but, on the weekend it's nothing but, burgers, hotdogs, and fries.

80% homo, 20% hetero, or vice versa. These percentages can be changed to fit ones level of bisexuality. Ex., you like guys and girls equally, 50-50. Almost equally, 60-40. You get it.

A blowjob that is mostly just a handjob.
My new girl went down on me but only gave me an 80/20 handy-blow. My old girl was all throat but this chick wouldn't put more than the first couple inches of my dick in her mouth.
