Clear the Cache - the act boys perform prior to their girlfriends coming to visit, just in case she uses his internet.
Clearing the Cache or "Deleting Internet History" is something all boys do to avoid awkward conversations trying to explain video links to "Plump Asian Butt Fuckers" or "Strap-on Bukkake Party"
Any woman that wants to check that her man has "Cleared the Cache" can check the internet history of his primary web browser.* If there is no or very little history of anything, he's just Cleaned the Cache.
*Boys will often direct people using their computer to use Internet Explorer or some other secondary web browser as this browser is not the browser they use to access their internet porn.
Dominant Ball - Guys have a dominant testicle. I didn't know if you realised this or not but I thought you should know. One ball hangs lower than the other, the dominant ball, which for the majority of men is slightly larger and usually the left testie.
The two balls often jostle for prime scrotum position especially amongst men who wear jocks or tight pants which, however gallant the less dominant ball is, will inevitable result in the dominant ball, or quall, victorious.
Oh, and the whole ball licking thing, it's totally not necessary but we appreciate it. We understand how gross our scrotum is, and given the actual marginal physical pleasure it gives us fellas (it's OK but nothing to write home about), big props to you ladies.
peace out. jkl.
