You know when somebody puts a diaper in the trash and they don't tell you about the surprise... So you start getting little whiffs of the diaper but it hasn't gone totally rank yet so you can't really figure out what or where the smell is coming from?

The first floor of my apartment building reminds me of that smell except there are no babies that live here, only old people... hmm... smells like someone needs to take out their garbage, because their Depends have gone sour and smell *rank!

*Cue the throw up noises
