A Bromageden is an epic dude party commonly consisting of 5 or more bros, one or more consecutive all nighters, energy drinks, and lots of video games. This level of enjoyment is only achieved usually one or two times a year. A girl arriving at any Bromageden instantly relegates it to just a party, as Bromageden are exclusively male events. The term was originally coined by a group of high school guys in northern Indiana who threw an epic party once a year.
when you throw yourself under the bus to help a brother out. Usually when this psycotic whore stalks your bro and his gf/her "best" friend. usually she is a kind of cockblocker, and you are your bro's savior, like a Jeezus.
When Jack asked Bill to take that cockblocker Elizabeth's attention from Jack and Jill, Bill knew how much of a bromageddon this would turn out to be, so he said yes.
If you or someone you know had to sacrifice themself for a bitch so someone else could move in closer with their girlfriend, you have seen a bromageddon
It's a mix of two words: Bromance (A made-up word for men who spend quality time together) & marriage.
Bromage sounds exotic and almost French in nature.
It is for men who share a "bromance" that have been friends for awhile (a year or longer) and they're in it for the long haul.
It's like a common law marriage for bros.
Christian: "Ya know Justin, we've been friends for over 10 years. I feel rather committed to this friendship."
Justin: "I feel like we have a bromage going on, man."
