"see that guy, he looks like a right fleg"

e.g. when it is a rainy and windy day outside, someone could say:

"That tree is flegging"

referring to the movement of the tree in the wind, during a period of wet weather.

Jen certainly flegged poor Bob - I heard she banged some random dudes in his bed while eating a turkey drumstick.

"Dinnae jump out at us, ya gave us a fleg"

You've been flegged on.

"Your such a sad 'fleg'with nothing better to do with you life than mock those less fortunate than you"
"Fleggies" are people who dont know how to be nice.
"Fleggums" Group of ignorant idiots.
"Flegettes" group of saddos with a low IQ.
"Fleg-worrier" A fleggie wondering if they are gonna end up disabled like the people that they mock

Oh man, my fleg is killing me.
