BULB

Full Form: Bar Umar Lanat Beshumar.

Meaning: Curses on Umar for all eternity.

BULB is often used as a hashtag in various social media platforms, mainly twitter. It is used by the shi'ites to curse one of the closest companion of the Islamic prophet Muhammad, Umar Ibn al-Khattab for his apparent wrongdoings to Fatima al-Zahra the daughter of Prophet Muhammad. They also blame Umar for the death of Fatima.

These views however, are rejected by the Sunni scholars.

Shia: Happy Eid al-Ghadir, #BULB.
Sunni: Here comes another shi'ite cursing the sahaba.
Shia: Noo!!1! We never curse the sahaba. Only shiraz-
Sunni: Cut it with the taqiyya, rafidi.
