פוסטמה
postema
a sour, sulking, joyless mood — or the person stuck in it · noun (feminine), also used adjectivally
The face that walks into a party and lowers the temperature two degrees. That mood, and that person, have one word in Hebrew.
די, אל תשב פוסטמה בפינה, קח בירה ותצטרף אלינו.
“Enough, don't sit there like a sourpuss in the corner, grab a beer and join us.”
Think of a time you've seen someone in full פוסטמה mode. What was the thing that finally made them crack a smile and rejoin the group?
