He's a DUmp male, so don't leave out the possibility that he could be on the rag.
I located a receipt from one of Atman's recent purchases.

Looks like he picked up some feminine hygiene products. It also looks like he knows how to use coupons to get through his "monthly" on the cheap.
(I
really don't want to know what he does with the peanut butter and sweet pickles)
