1) Abbreviation for the non-profit organization People for the Ethical Treatment of Hedgehog.
This organization was started in 2009 when many concerned people began to notice more and more Hedgehogs being mistreated, beaten, punted, tortured, and made fun of, a lot.
2)Slang term for a street drug made of many common household cleaning chemicals that "makes you totally retarded dude!"
Some biologists believe all Hedgehogs to be "born with a fucked up brain" which is why the drug name was taken as a spoof of the non-profit Hedgehog protection organization P.E.T.H.
