I have big balls and a do what ever I want..when you dad ask you to do something and you say,, but way me??he say,, Well because of my focking balls!!.. That's when you do something,,,ahuevo!!Now a frien of you ask you to drink a beer, is Wednesday you got things to do.,,But you got big balls and take the decision to do whatever you want right?? So you friend ask,, hey you want a beer??? You say ahuevo!! And I wanted cold please. :-) that's when you used ahuevo as a affirmative way....let me know if you digg it please.
