What is Vegas Wife?
1.
A stripper, more specifically the individual stripper you end up giving more money to on your trip to Vegas than you spent on your wife's/girlfriend's last birthday present. Most likely she was the one in the club that convinced you that "she's really into you" and let you touch her boobies, despite a strict "hands off" policy.
"Man, I really hope my Vegas Wife TeeKay is working at the club tonight. She really gets me, not like my girlfriend back home."
