Apparently.
I'd also observe that they tend to hang out with lots of friends even when there is not an impending conflict.
The formula is something like:
Gringos - One per car.
Hispanics - One per seatbelt, plus one for good measure...
When I was in high school a freind of mine (white) was jumped by 6 guys (white) for dating the wrong girl (one of the jumpers old girlfriends).
He told me and some other freinds (all white) and we collected about 15 guys to find these 6 guys (everyone is white).
These 6 guys find out we were coming to thier neighborhood (a white neighborhood) and they had at least 30 guys (all white) to meet us.
Most of my friends split (white and not too stupid). I stuck around (white and stupid or too young to know better you decide). Well we fought, me and my friends lost and we left never to venture into that neighborhood again.
My point is, escalation by bringing more freinds is not a Hispanic thing, its a teenage boy thing.
