Date bomber. A date bomber:- a person who mingles their way into a conversation whilst you are on a first date. (Person is usually known to one of the two dating, but not always the case could be a random stranger.). The objective of the date bomber is to ask both parties questions about themselves. Thus rendering conversation to a nil when date bomber has left, creating an awkward silence for the reg of the date. Would like to thank the stranger who date bombed my first date with someone in ages. I truly think you are a dick.
