A term that gets a lot of (well-deserved) patriotism from the writers of Urban Dictionary. It refers to those kick-ass people who live in Wales (no duh). I could go on, but there's thousands of other Welshmen and Welshwomen (I'm not sure if that's a word) out there waiting for you do hear their story. Up Cymru and to hell with the English!
Just look up and down the page, there's examples of Welsh people all over the place.

If you are non-white you will find that welsh people are similar to the english but more cultured and honest. They do not shag sheep, and all the welsh people that I have met are very sexy, especially the blokes who play rugby.
They are very friendly and giving, however they are a little simple and inclined to drink too much (from what I have seen).
Sandrine: cummon shandice lets go and perv at them welsh blokes playin rugby.
Shandice: oooh, watta a minge tease.

When I married a Welsh woman, I felt inclined to adapt to her slang, folk dance, roast culture and Welsh intercourse practices.
