These two words mark the end of a suicide bomber's life. He or she will scream anything related to their god and detonate their bomb which is attached to their body, sacrificing themselves for religious reasons. It is beloeved that doing so will reward the bomber with 72 virgins in Heaven. ( Or so it is said )
Suicide bomber: "Allah Akbar!!!" BOOM. He flies up to heaven to be greeted by 72 computer nerds..."OSAMA!!!!"
Nerd: "Yet another result of allah boom huh?"
