Gaucho Pants 

Skirt-like pants that usually end at the calf. These pants feel like leggings at the crotch area but flares down at the legs.
Gaucho Pants come in different colors (Black, Brown, White etc.) but the most common color is black.
These pants are typically worn during the spring and summer but can be worn during the fall and winter with calf-length boots.
One of the most comfortable pants you will ever wear.

Gluck Gluck 10,000™ 

Similar to the famously known Gluck Gluck 9000, the Gluck Gluck 10,000™ uses the force of an unimaginable number so much so, that it dissects the penis, vacuum seals it, and leaves a nub (A Dicklet, if you will) in place of where the man once had his Genitalia.

"Aye Tony! You didn't warn me your girl coulda done the Gluck Gluck 10,000™! Now i'm just a fraction of the man I once was."

Gaucho Slap 

The "Gaucho Slap" is commonly performed when a man and a woman are engaged in normal sex using a condom. Normal intercourse is the name of the game till the male ejaculates, at which point he removes the condom and whirls it around his head gaining centripetal acceleration (like a gaucho) once at maximum velocity he releases the condom, sending it flying into the face of said woman causing a "slap" noise along with an explosion of semen and other bodily fluids that will be sure to enrage any lover.

Gee wiz! Did you hear about Jill? Her and her boyfriend Fernando recently broke up because he Gaucho Slapped her, totally ruining the moment.
