A person who spends a large proportion of their day puffing small gusts of air from their posterior and pretending it wasn't them (despite the accompanying soundtrack/telltale stench).
Non-stinky person: Dear me, someone's a smellypuff today! Where's the Febreze?
Smellypuff:Um, yeah, think it must be the cat. He went out for a vindaloo last night. Felix, control yourself! Think I can hear a trumpet playing outside ...
