swé

Swé does not have a rigid definition. It is used by Dublin and Bray skangers as a "filler" word, in a similar way to how people use the word "well". Swé is used by non-skangers as a reference to skangers. It is also used as an adjective to describe skanger-like behaviour.

Swé is pronouned a little like "shway" or "shwaaah".
Skangers having a conversation:
"Aah swé lads, lets go cruising for birds."
"Swé!"

D4s conversing:
"Your man is like such a scobe. He's so swé."

More D4s:
"He's littering. Like, how swé"
