Manspreading is when a guy sits way back and sprawls his legs out. Jared does it all the time because oh my god his legs are so long…mmm. Sorry. Where was I? Oh yeah! That’s what it actually is but it sounds sort of dirty so it was already hilarious. Mayonnaise is also known as sandwich spread but once again, mayo can be part of dirty jokes because of how it looks. So there you go- hope that helps.
