In which Men think that girls are hanging around in their bras and panties and start throwing pillows at eachother progressivly getting more violent until bras rip off and turns in to wrestling on the ground in mud.

Joe: Oh man yea!! those are so hot!!
Tammy: oh yea you should've seen the pillow fight we had over at Callies 2 weeks ago...that was hot
