I'll be the mature cannabis smoker and give an educational response.

Skunk generally refers to a high grade form of cannabis (ie Kind Bud). There are Skunk strains but as I said before, its usually a general term for just really potent weed.

The term Skunk is more prevalent amongst the British Isles from what I hear. Haze in the States is also used for the same thing. If you get Haze, you more than likely aren't smoking the actual Haze.
