An alcoholic drink.

In a shot glass (NOT a cordial glass):
1/2 shot Bailey's Irish Cream
1/2 shot Kaluah
Topped with whipped cream as high as you can make it.

After the shot is made, the drinker can do a liptease, and lick some of the cream off the top. If the drink has been bought by somebody else, this is almost a requirement.

The drinker places her hands behind her back, leans over, wraps her lips around the shotglass and straightens up, tilting the head back and swallowing the shot in one gulp.

This is a good way to get free drinks, just make sure you don't choke. It takes a while to master the technique of doing this gracefully and looking sexy.

A casual invitation / threat used by an individual that is not afraid of fucking someone up.

The guy unzips his fly and the full shot glass is placed in the opening. You then have to take the shot without using your hands.
