concoctail, meaning quite literally, to create a previously un-named cocktail out of various alcohol and drinkstuffs in an attempt to become intoxicated.
The literal act of concoction, with a variety of spirits, and one or more mixer liquids.
'We were all real poor, so we just dug out all the booze from the liquor cupboard, and put it all together...we made a wicked concoctail!'
'Nah, it doesn't have a name, we just slung it all together...it's a concoctail, really.'
An assortment of various edible material, mixed together in a plastic bag of any sort, proceded by mashing of the materials in the bag. The concoction is then dropped in the crowded hallways of Kingwood High School by the concoction triumvirate-Sam, Andy, and Chad.
Girl: "I'm so hungover and I can't remember anything from last night. What did I drink?"
Other Girl: "I think vodka, gin, Fireball, maybe Windex. Girl you gotta be more conscious of your concoction or you'll end up waking up in a Mexican jail."
