Slang for the opioid based drug/plant mitragyna speciosa AKA kratom. It gets its nickname from the smell of the ground powder that smells just like a llama. It produces short euphoric highs and is legal in most states.
Example 1:
Dan: Hey do you want any kratom?
Nate: No that smells like a petting zoo.
Dan: More for me I guess
Example 2:
I havent shit in over a week because I take an ounce of petting zoo every day.
