1. It's like a lubatzee or a muroni or a raitzee or a dabaitsuh or et cettera... Essentially, baitsuh is just a random word to describe emotion without putting a formal nomenclature to it.
Baitulmuqaddis, also known as al-Quds, is the capital of Palestine. It is well-known for Al-Aqsa Masjid, one of the holy sites along Makkah and Madinah.
Sadly, most of Baitulmuqaddis is illegally occupied by Israel. They purposely changed its name to "Jerusalem" and made it as their capital. No, this is NOT acceptable at all.
Derived from the slang 'bait', a person of questionablejudgement; a liability and embarrasment to others around him.
Thus, 'Baitster' refers to an individual who has consistently exhibited 'baitness', ergo, 'baitster'.
