Recently a lot of diaper posts have been mistagged with fart due to a number of white puffs coming from the diaper of a character in the image. These puffs typically represent a puff of talcum powder that gets shaken free due to movement or when the diaper makes contact with something; a hand, when a character sits down, pressed against another diaper, etc. It seems the air_puff tag has started to be used for related posts, but I feel that it's a bit too vague and generic for this exact situation. I propose a tag such as diaper_puff to represent this specific puff that comes from diapers and typically represents talcum powder. If there's no push against this, and there's no other suggestions, I'll create the wiki tag for diaper_puff and sort out the mistags myself.

Examples of the mistags are here: (note that these artists don't draw fart content, so don't worry if you're squeamish)
