smack your melon 

To "smack your melon" means to hit your head, or noggin on something hard enough to cause a negative physiological reaction, such as a concussion, any cut or abrasion on your scalp, seeing stars, or even just getting a noticeable headache thereafter. It is usually caused by an inadvertent or unexpected action, such as tripping and falling down, being the victim of a noggin knocker, hitting your head on the dashboard or steering wheel of a car during a crash, or even misjudging the height of a tree branch, or some other low-hanging object, and stupidly hitting your top knot against it while passing by.

Hillary proved that if you smack your melon, you will not have to testify, at least until you recover from the ensuing concussion.

shmecka 

Taking one's penis freshly coated with vaginal juices and smacking it across the face of either the female whom the juices came from or another person, making a wet smacking sound.

After a round with Linda, I nailed Bob with a shmecka while he was sleeping on the couch.

Estrogen Smack 

An Estrogen Smack is when a male gets full on bombarded by a lot of women (Not in a sexual way.) to the extent of him just saying "I'm done." and is really annoyed with all females for a short period of time.

The cure for a hard estrogen smack is basically... This guy needs to just be a bro for a few hours. Odds are if you've been Estrogen Smacked, you're a really nice guy with friends that are girls, you're not a nerd or anything, you just don't sexually exploit women that often.
You have to chill with your bros, eat sandwhiches made by woman and just be a dude. Try not to be a dick or else those women that smacked you will do it again more angry.

One night on Facebook, Ben was Estrogen Smacked. It was horrible. He had 7 girls talking to him on chat about how amazing their boyfriends are and how cute their cat is. After Casey kept writing Wall post after Wall post, Ben /rage quit and needs to go be a bro for a while, maybe do some falcon punching, or get oral sex while eating doritos.

Poor Ben. He feels like he lost his manhood.
