Peeing against a wall - Mashtin Bakir - מַשְתִין בַקִיר
This is actually a biblical slang word. I haven’t heard it used outside of the bible but I really like it. It’s a derogatory term, replacing calling someone a dog (because dogs pee on walls). It isn’t that relevant to be honest, but it has a rather nice ring to it.
“Therefore, behold, I will bring evil upon the house of Jeroboam, and will cut off from Jeroboam him that pisseth against the wall.” (1 Kings 14:10)
