oorah

A motivational cry used by the United States Marine Corps. Sometimes also used as a general response to an order or question. Recon Marines in Korea (1953), traveling by submarine, often heard the dive klaxon which sounded like "Aarrugah." These Marines began using the word as a motivational tool, but it was too long and slowly became modified into what it is today. It was popularized during the 80s and 90s.

ootman

Ootman is a african god of memes. Ootman is a strong god, before he became a god, he died by getting ran over by a stampede of elaphants while using his windows vista playing roblox. Ootman will smite you if you claim that he doesn’t exsist. The name of his religion is ootmanism. To praise ootman, you make a door, bang on it for a couple of minutes while yelling “ootman open up”. Then leave gifts at the door, than listen to “the lion sleeps tonight” while in a triangle, square, or any shape with more than 2 edges. Ootman loaths straight lines because he got killed by a line of stampeding elaphants. Btw this is a joke so dont actually do this

Johnny: lets praise ootman
Max: ok
