3XL? No, Boogie hasn't been in a 3X since high school lmao. 3XL is like your fat loveable uncle that takes all the leftovers home after a holiday, it's like normal fatass, not "Jesus Christ, what have I done do deserve to be in the presence of this disgusting ham planet?" tier that Boogie is in. That's a 5XL shirt. How do I know this? I went to their merch shop and the largest size they have is 5XL. He fills that bitch out. If you hold your ear to the monitor, you can hear the faint shrieks of the cotton threads as they struggle to hold back his tit meat. His other shirts generally look like someone draped a tarp over him, because nasty fat fuckers prefer to hide their disgusting folds by wearing loose fit clothing, which tells me he likely orders up a size.
TL;DR: that's a 5X shirt which is a size too small for him, his normal size should be 6X, but he likely orders 7X so he can look like a boulder with a tarp over it instead of a melted lump of wax. He's so much fatter than you think he is.
