The word can be used competetively in "bogies" style competitions. The aim being whoever shouts "BOYZ" the loudest wins.
Sometimes these words are ussually uttered before using the word Boyz, bur hur hur bur hur hur...... BOYZ!!!
When said, the word may sometimes be heard wrong. Ussually misheard as the word "Books".
"SO YOU'VE BEEN CHEATING ON ME ALL THIS TIME!?!?!?"
