Jacklung

My cousin is a Jacklung. He talks nonstop even when no one is listening.

She texted me 20 times about her cat. Total Jacklung.

My teacher called me a Jacklung for talking during the test.

He said he knew how to fix the printer. Total Jacklung.

My friend thinks he's a genius. He's just a Jacklung.

She tried to explain algebra like it was easy. She's a Jacklung.
