fart bloom time

The time from when you fart till the time you actually smell it. Usually it's instantaneous but could take a couple seconds.

Picture a fart being released and "blooming" upwards like an atom bomb.

Man, that fart had some bloom time. I almost thought it wasn't going to have any smell at all. That was a long fart bloom time.

That fart smelled pretty weak at first but as the bloom time increased it got richer and richer...damn.
