A trip or adventure by a group of bros, usually made for doing manly tasks such as canoe racing, bear hunting, making their own beef jerky and riverboat gambling trips. The members of the manscursion must yell "manscursion!" before every task for it truly to be one. Alcohol is encouraged.
Jim: Hey bros, what are you doing today?
Group: I don't know. I think we were just going to watch Titanic.
Jim: Fuck that! Let's go bear hunting!
Jim: Let's down some shots first!
