Union Jake

(N) Someone who takes part in a Union Jake-off, then feels dirty afterwards and goes to vent about it on a disreputable forum filled with 14 year old nerds who have never gotten near a woman.

I saw a group of Union Jakes yesterday.

England is represented by the flag of St. George
A red cross on a white ground

Scotland is represented by the flag of St. Andrew
a diagonal white cross on a blue background.

Ireland is represented by the flag of St. Patrick
a diagonal red cross on a white background

The Welsh dragon does not appear on the flag because when the first Union Flag was created in 1606, Wales was already united with England
Therefore Wales is represented by the English Flag

The "red Diagonal lines" are not from wales. Thats thought up ignorance by Gumba Gumba
