When a vegetarian or vegan instantly becomes enraged and preachy over the smallest mistakes (or even unfamiliar knowledge) about their particular eating habits. This behavior is usually followed by either an angry or arrogant retort, correcting the offender's mistake. This behavior is most common in vegan culture, primarily caused by being mistaken for vegetarians.

Dude, seriously, there's soy in 7-11's chili. You need to put your vattitude in check.

I'm not going to that market anymore, the staff has a weird vattitude about them.
