Mutual bothering

Usually found in siblings, a balance found between people in which they annoy, and get in the other(s)' hair to their exact tolerance where they can take no more, but expecting the same done to you

My brother and I have a system of mutual bothering where we annoy the crap out each other until the other is about to snap.

mutual crust

Mutual crust is formed when you don't pull out after sex and fall asleep. Body fluid from both parties join and dry to form mutual crust all over their private parts.

Jack and Jill woke up Saturday morning and were stuck together by their mutual crust. They had to waddle to the shower together to free themselves of each other.

mutual hosting

When a corporate boondoggle is so egregious and over the top that one firm cannot afford to host the event alone, either due to the actual cost or potential liability, the event must be mutually hosted by multiple firms.

Due to the level of drinking involved at the corporate ski trip, we are going with a mutual hosting plan for this boondoggle.

Mutual combat

when two individuals intentionally and consensually engage in a fair fight

Originally added to courts so you wouldn't get a murder charge when engaging in a duel in the 1800s

Coke dealer: I challenge you to a duel

Drunk guy: mutual combat isn't even legal here, don't kick my ass
