Their popularity came from the effect wine has on women. (If you plan on getting layed - what other reason is there?, you have to be careful that they don't get sick and pass out.)
About a year later, Boone's Farm and Annie Green Springs appeared on the market in one liter bottles along with a less well known wine drink called Ariba, which was 20% alcohol.
The latter had a reputation as a "sneaky Pete" because you could slip them to a date who could normally guzzle the 11% beverages all night while keeping her mouth running and her knees together.
However, upon the evolution of the gibberish part of the english lanugage, it has been taken to mean:
sexy/cool/awesome/hot( sizzle with a "w")/ 'Sweet!!!'
in no particular context.
Plus its a word that's fun to shout out and helps in the formation of saliva suds :)
n. the motion required to propel a caster board forward.
"You're swizzle needs some work, but it's not bad for a beginner."
