επαΐων

During the time of Coronavirus, I learned another word for expert. There's εξπερ, of course, and also επαΐων! 

αΐω to perceive

υποκείμενο νόσημα

underlying condition

the days of COVID-19 teach me medical terminology, of course. 

μπάφος

Pandemic vocabulary: I learned the word for joint of marijuana from the quarantine joke below. 

τσιμπούκι

Watching rebetika videos with Loukia as a "therapy" during the Time of Coronavirus, we listened to Ναργιλέ μου γιατί σβήνεις, which has the word τσιμπούκι, or the hose of a hookah.
