A pandemic that recently morphed from the H1N1 virus. Symptoms of swag flu include:

Spending copious amounts of money on jewelry.

Ordering expensive drinks consisting of Hennessy and other cognacs.

Driving cars that you cannot afford.

Disrespecting women.

There is no cure for swag flu.
I can't come into work today because I've got the swag flu. Also, I just leased a new E-Class that I have no way of paying off.
