When you are in a relaxed, comfortable state of mind, watching television and a commercial airs with an extremely attractive women actress. Suddenly your hormones become hyper-active and the desire to engage in sexual intercourse becomes intense. The transition from mellow to aroused after observing a hot girl is know as the Hot Girl Affect.
-Hey my bad man I think I clogged your toilet, wheres the plunger? Hellooo you here me? Eww why do you have a boner?

-Oops sorry, Carmen Electra was just on a Lectric Shave commercial and I started to day-dream.

-Its cool dude, the Hot Girl Affect gets to even the best of us, no worries, but your toilets still clogged...
