That's why I want to know his reasoning. Has he been thinking about this for a while? Is it a New Years thing? Why did he go vegetarian? The world wants to know :V
I hope it wasn't just for New Years. Probably the least substantial reason to do anything. January 1st: "I'm gonna quit smoking." March 1st: "Mmm fuckit, Marlboro please." There are plenty of reasons to go veg. Just pick one you are passionate about and commit.
He did it for ass pats. For all we know, the fat fuck probably downed a burger just now and is too busy grazing on the flesh of a thousand abused livestock than to answer everyone's question as to why he's pretending to be a vegetarian.
