Cover art for Antlion lyrics by Dance Gavin Dance

I think this song is comparing a woman to an antlion, hence the song title.

"There's a bomb in my face, decorated in white lace" right there he's explaining that she is attractive or seems pleasant, but in reality she's trouble and she conceals it.

"When people they look at you, Do you think do you think of food?" again, this is comparing her to an antlion, "devouring" her victims, when she sees people she seeks to destroy them.

My Interpretation

yeah, i'm pretty sure you're right on. i have no idea how some people think its about an eating disorder.
