Cover art for Beto II lyrics by Fair to Midland

I'll go line-by-line, but the abridged version is something along the lines of how a kid is deemed a criminal because one[or both] of his parents are in jail and decides to inadvertently prove them right.

reach. go on.

hands don't match go and find the bars that make us hunger[this is perhaps the parents telling the kid something in hopes that he understands why they're in prison?] maybe with knots and uniforms[maybe other kids are making fun of the POV character, saying if he wants to be closer to his parents, become a prison guard] and if i may add, well i've got a big gun and i know just who i'm gonna use it on maybe it'll make for the better.[the kid then retorts that he has a gun, and he knows how to use it, and that he'll shoot certain people]

the beggar always has his strength his ambition is tapped[the kid is easily manipulated because of his hunger for (his parents') attention?] always occupied on the john[he hides in the bathroom because he is bullied a lot] while he's there let's take advantage.[so eventually the bullies catch on]

we are not the bringers of second chances gone within a moments notice[not sure what this line means] and if it's genetic then i'll be fed through those same bars how appropriate.[the kid muses on how all these scientists keep talking about criminals being genetically criminal, and if this is all true, then he has no choice in whether or not he becomes like his parents in prison]

days in march go, leave us in debt and always hoping maybe in ten more years i'll know him[the kid misses his parents, and the parents feel the same way...and neither feel like they know each other] and if i may add well I've got a big syringe to show to all my close friends maybe i'll upgrade near the kiddies[the kid starts doing drugs to look tough and perhaps because of his lonliness, and shows off whatever drugs he's doing in order to project this image]

i'm still because i'm frozen[again, not sure what this line could mean]
