aka (euphemistically) pain in the butt. A true pain, something damn boring, annoying, offending, labored, troublesome, exhausting or if something just extraordinarily sucks!
Has gotten 'popular' thru J.D. Salinger's catcher in the rye, said various times by the story's main character Holden.
Me: Dude, this math test was a royal pain in the ass!!
Geek: How come I aced it?- $20 from my dad...
Spanish for "my people", talking to or about people close to them, which can be family members, but normally ain't. Mostly used by chicanos or other hispanics in the sense of "my homies", "my hood" (mi barrio) in the streets of major, latin-impacted cities in the US, like LA or MIA.
What??? Those mofos from the valley want trouble??? I'mma holla at mi gente to get some backup from the barrio in East LA asap!
