T-Rex: Petrichor is the pleasant smell that you get when rain falls on dry soil!

T-Rex: Therefore, the regular smell of dirt BEFORE rain is prepetrichor!

T-Rex: But, we remind ourselves, the future is unknowable and it may never rain again. Therefore, the standard smell of dirt is better described as postpetrichor, referring as it does to a known and previous rain.
Dromiceiomimus: What about the nice smell of dinosaurs and humans after the rain?
T-Rex: Dinopostpetrichor and anthropostpetrichor, respectively.

Utahraptor: Are you relating... ALL smells to petrichor?
T-Rex: JUST WATCH ME.

T-Rex: We like our own smells due to autodinopostpetrichor, and we dislike the smell of garbage because of how far it is acceptability-wise from nice rain smell. Therefore, garbage smells antipostpetrichor. And smelly humans are antianthropostpetrichor.

T-Rex: You may wonder if I am accepting feedback on these new words.
T-Rex: Friends! The answer is "oh hell no"!!
