Cover art for Beat Me Up lyrics by Allison Iraheta

In it's most basic form, people are going to take it as a song about sex like "hpman247" stated or domestic violence. Allison herself said it's more psychological or emotional abuse, which is equally wrong as domestic violence. Personally, I know that this happens to tons of teenagers. Girls, for some reason (and I am one and I don't even know why) still like a guy even after he's a jerk to them. This guy could be their boyfriend, their crush, whomever. It's like the quote stating something among the lines of "How could you break my heart, but I could still love you with all the shattered pieces?" The guy could be cheating, not calling, leading the girl on, or even destroy the girl's heart..and the girl, for some reason or another, still loves him. She still thinks he's "everything" even when he's hurt her...ergo the line "And I really don't care what they say about me 'cause he gives me everything I want. And they don't know what it's like when you need somebody to the point they can do no wrong" It's horrible...but it happens.

My Interpretation

I completely aagree with your meaning of the song, but I also just want to sat that Allison basically said in her interview with Popeater that the song was about sex. But all songs have multiple meanings and should be taken in as the individual listening sees fit. :)
