[Instrumental] [Harsh vocals] I’m sittin’ here, lookin’ calm and cool, Playin’ the part, like a goddamn fool. But inside my head, it’s a fuckin’ mess, Tryna keep this filthy mouth in check, no less. One wrong word, and it’s all goin’ south, My brain’s like a sewer, but zip up my mouth. Gotta chain these thoughts, keep ‘em locked tight, Or I’ll be droppin’ shit bombs left and right. [Pre-chorus] Smile on my face, keepin’ it clean, But my mind’s in the gutter, obscene as it’s been. Gotta lock it down, toss out the key, ‘Cause what’s in my head ain’t fit for TV. [Chorus] Filter, don’t fuck up, bite my tongue,** Keep the shit down, don’t let it run. Gutter mind’s screaming, it’s breaking through, Tryna keep it PG, but fuck, it’s you.** Filter, don’t fuck up, can’t slip now,** Dark thoughts rising, can’t be let out. Normal on the outside, devil in disguise, If they only knew what’s behind these eyes! [Harsh vocals] Inappropriate thoughts, they sneak through the cracks, Gotta stuff ‘em down, no turning back. They say read the room, but my GPS is broke, One wrong word and I’m the butt of the joke. [Pre-chorus] They think I'm a saint, but I’m barely contained, Every grin’s a mask on a runaway train. I’m dancing on the edge, one step and I’m gone, Trying not to drop bombs, just keepin' calm. [Chorus] Filter, don’t fuck up, bite my tongue,** Keep the shit down, don’t let it run. Gutter mind’s screaming, it’s breaking through, Tryna keep it PG, but fuck, it’s you.** Filter, don’t fuck up, can’t slip now,** Dark thoughts rising, can’t be let out. Normal on the outside, devil in disguise, If they only knew what’s behind these eyes! [Bridge] I’m teeterin’ on the edge of the line, Bite my tongue, actin’ like I’m fine. They say "speak your mind," but if I dare, They’d run for the hills and leave me there [Chorus] Filter, don’t fuck up, bite my tongue,** Keep the shit down, don’t let it run. Gutter mind’s screaming, it’s breaking through, Tryna keep it PG, but fuck, it’s you.** Filter, don’t fuck up, can’t slip now,** Dark thoughts rising, can’t be let out. Normal on the outside, devil in disguise, If they only knew what’s behind these eyes! [Outro] So I’ll keep smilin’, nodding along, Act like there’s nothin’ wrong. But inside, it’s a circus, a war zone too, Just tryin’ to keep the shit from breakin’ through. Oh, filter, don’t fuck up now... Don’t let ‘em see what I’m all about.
