An abbreviation for "Post Nap Hair", or "Post Nap Hurr" if you're from my hood. When you wake up from a nap, your hair is srsly fucked up. Your boyfriend/girlfriend might think it's really cute, but you can't trust them because you know it's fucked up.
PNH does not actually require sleep. It also occurs after srsly good sex or a night of hard partying.
Them: Did you just wake up?
You: Why?
Them: 'Cause you got some serious PNH.
A trip to a grocery store, convenience store, or gas station for the sole purpose of buying an excessive amount of junk food and sugary drinks, usually with friends. A chud run often happens late at night and ends with everyone involved hating themselves afterwards.
