NSAB 

Non-sexual adult baby (those who appear to be paraphilic infantalist but lack the true paraphilia). Pertains to one who like baby-like; enjoying wearing and possibly using diapers, sucking pacifier, drinking from a bottle or sippy cup, sleep in a crib, ect. This is an accurate definition for those that appear to be paraphilic infantalist but lack the sexual elements necessary for a fetish. This is not a fetish, this is a lifestyle.

A man who wears a diaper shirt and overalls during the day and a blanket sleeper at night is showing elements of NSAB.

A girl who is not a drug user who is sucking a pacifier is showing elements of NSAB.

NSABJ 

No strings attached blow job

I did so much work around my neighboring MILF's house that she gave me a NSABJ for my effort.
