boyo 

The term "boyo" is a part of "Wenglish" (Welsh-English) that has simply grown from a Welsh take on the English word "boy". Although perhaps not widely used today, it is used to address someone, not necessarily young, frequently with negative connotations.

What ya doing there, boyo? (A non-welsh person to a welsh person (both grown men)).
