"'What you got under you shirt' could mean fat(lol)"

Uhhmm I think he's talking about a gun under his shirt lol.

@EvilZombie i was thinking bomb but gun makes more sense

@EvilZombie I think by that he meant selp harm marks or maybe bruises and scars from abuse ? Definitely not the "fat" one

@EvilZombie I thought maybe boobs
