Wait, there's only 10 different types of smells!? See what they are here:

You probably know that your taste buds only pick up five flavors, salty, sour, bitter, sweet, and savory and everything you eat, drink, or randomly lick falls into those categories. Turns out the same thing happens with smell. Scientists at Bates College in Maine have found that there are really only 10 SMELLS in the world, and everything you smell falls into one of those categories.

The 10 smells are:  

Fragrant, like flowers

Woody 

Lemon and citrus 

Other fruit 

Chemical 

Mint 

Sweet 

Pungent 

Popcorn 

Decayed

Yes, for some reason popcorn gets its own.  And decayed sums up pretty much everything BAD, from a rotting corpse to the rotting smell of the room after everyone ate at Chipotle.
