Almost like regular mayonaise, but there's a catch. Payonaise is actually the product you end up with after you've used your penis as a butter knife to spread mayonaise on your sandwich. Take the P from penis and the ayonaise from mayonaise and what do you get? Payonaise. You could also use this as a slang term for man juice.
What the fuck? This shit taste like payonaise.

Short for "I Laughed When I Read That." This term is common among a more sophisticated group of internet users. It is to be used in place of, but not entirely seperate from lol. See "ILOLWIRT."
