When someone claims to have changed old behavior, but is actively engaging in said behavior secretly. This term can be used in a variety of circumstances, but is particularly appropriate when referring to sexual relationships between clients within a rehab center.
Tim told me he wasn't flirting with Sarah anymore, but I caught them talking dirty over facetime - he's noodlebacking hard.
There once was a boy, we'll call him "Zach". Well "Zach" asked this beautiful girl out. We will call her "Sarah". Well they dated for 2 months. 2 long, wonderful months. Zach would always tell Sarah how much he loved her. He would always show her too. Well Zach was also a notorious liar, and once they broke up, the lies came pouring out. He was a pothead, and he lied about that.
But the moral of the story is,
Zach had butt sex with some ugly chick named Natalia at the ymca. yeah gross '_'
well, he has diickk herpies, and she has butt herpies.
