"And I promise not to tell anyone that you're not so unpleasant a guy when you want to be," Regulus replied, casting Severus a conspiratorial wink. Then he followed it up with a snicker. "Tea leaves can bite my scrawny arse." The snicker was followed by a rather uncharacteristic snort of amusement.
The younger Black listened with rapt interest as Severus described the effects of the liquor he called tequila. It sounded like the muggles had created some kind of magic of their own practically. This he just had to try.
He reached out without hesitation and picked up the shot glass. He tossed the liquid down his throat in one fluid motion, then immediately followed it up with some loud sputtering.
"Gods, that's bloody awful!" he exclaimed, cringing. Then he shook his head as if shaking off the taste of the tequila. However, despite that display, he soon pushed his shot glass back toward Snape. "Hit me again," he said with a mischievous grin. Oh yes, the alcohol was starting to take effect now.
