Inspired by a September 21, 2010 episode of The Colbert Report, a Beekeeper's Jacket is essentially slang for the fellatious act of oral sex, known commonly as a "blowjob", "BJ", "Head" etc,.
I heard that slut gave him a Beekeeper's Jacket at Rick's party last night.
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
