Cover art for Antlion lyrics by Dance Gavin Dance

I interpreted it as a guy getting married, being confronted by a guy that his wife was cheating on him with and having then a breakdown.

"Somethings wrong, Somethings wrong There's a bomb in my face, decorated in white lace" White lace being the wedding dress, and her/the marriage being a timebomb until the affair is exposed.

"Stretch yourself as far as this can go at night" Wedding night.

"Hey is that your lady? She gave it willingly" The new wife's bit on the side telling the groom about the affair.

"hey wait I've got the parts, to fix your head, to fix your head to fix your head

wait right here, I'm going to explode wait right here, I'm exploding" The guy having a breakdown.

Could be wrong though, both pageweknew's and Jericho_Reivaj's interpretations make sense too.
