Split-fingered fastball

A baseball pitch that looks like a typical fastball to you, then mindfucks you by dropping out of the strike zone as you swing, utterly humiliating you and making you look like a third-rate bushleaguer. Swinging at this pitch and missing is like getting hit in the face by a freight train--you should have seen it coming, but it's just too damn good for you.

You need an example for this? Seriously? Fine. That thar guy on the mound sure throws a mean SPLIT-FINGERED FASTBALL. Are you happy now!?

Finger Splint 

A veteran move to say the least. Often used after a long night of alcohol consumption. When a gentleman's erection is non-existent, he places his index finger under his limp noodle to "splint" it in order to succesfully guide it into his partners vagina in hope that once inside, he will wake up and perform.

"Man I was so wasted last night that I had to go with the finger splint. Even then I couldn't get it up! Needless to say, I was embarassed.....but not as much as she was!"

Finer than a dog's hair split three ways 

Means that something is very fine, or that you feel excellent. If someone asks how you feel and you simply say "fine", you might just be saying it out of convention. Adding the "dog's hair split three ways" shows that you actually mean it.

Another form of the expression is "finer than a frog's hair split three ways", although literal frogs do not have hair.

You: How are you doing today?

Me: Why, I'm doing finer than a dog's hair split three ways!
