That's not the case. The case is that there are 760 different possible scenarios regarding different types of briefs, shorts, pants and pamps, two of which are secret hidden "pantsless teasing" (one front and one back; not really bottomless in either case, though).
Actually, Poofy is one of the possible states/scenarios of diapers alongside Clean (or Regular), Bulgy, Constipated, Cummy, Desperate, Gassy, Messy and Soggy; Poofy, however, only applies to pamps because I can't think of any underwear being poofy without pamps.
Constipation: When you want to use the bathroom but you're struggling to do so.
Desperation: When you need to use the bathroom but you're struggling to hold it.
As for Swim Pamps with any Briefs, I'd say Swim Briefs would be the best match.
2) Pullups are a type of diapers to me, contrary to some other people's beliefs.
3) Both Bulgy and Thicc can be in any state, clean or not.
4) You can choose any type of briefs you like, whether they can either be underwear or outerwear.
For Example:
Basic Pamps
Bulgy Basic Pamps
Constipated Basic Pamps
Cummy Basic Pamps
Desperate Basic Pamps
Gassy Basic Pamps
Messy Basic Pamps
Poofy Basic Pamps
Soggy Basic Pamps
If this is just for fun, then alright. But, I cannot draw to save my life.
Desperation: When you need to use the bathroom but you're struggling to hold it.
