A Texas Curveball is an uncircumcised dick with foreskin all the way up to the urethra, with a large round head and a thin crooked shaft. So-named due to the penile deformity resembling the curveball arm configuration of MLB pitcher Clayton Kershaw, a Texas native.
Someone that is fuckable when graded on a curve. When you're somewhere that none of the guys/girls are attractive, so you pick out the least unattractive and go for it.
"None of these girls are hot, but I need some ass tonight and that chick is curvable."
A pitch which is doctored by the pitcher to make it have a bending motion as it comes to the plate.The pitch is thrown with a different grip than the fastball in that a pitcher wedges the ball in between his fingers and delivers the pitch as if he were slamming his fist down on a table. This creates topspin on the ball which makes air moving around it curve to the axis rotation of the pitch.
"The only reason why the batter is the underdog in this game." ~Warren Spahn, Winningest lefty of all time
"Barry Zito's curveball is unhittable!"
"That curve he snapped off was perfect! Nose to knees..."
