Song: "Smell Yo Dick" (2007)

Though comedic in concept, women have been smelling their man's dick for years to find evidence of infidelity (See: Mötley Crüe fucking burritos to mask the scent of groupie poon from their girlfriends). It's not a terrible way to go about unearthing the truth but it certainly doesn't end well either way.

Here's why:

1) He's cheating, and you now have the musk of another woman's vaginal juices trapped in your olfactory.

2) He's not cheating, and you now have that sweaty-scrote, boiled peanut scent trapped in your olfactory.

Ladies: Stop Smelling Dicks. Track the GPS on his phone instead.
