Collimating lens

A lens which focuses light rays from a source into parallel paths, thus focusing the image relayed at infinity. Highly useful in Head-Up-Display systems, for obvious reasons.
This will be the 2nd in my series of largely useless technical jargon, which will continue as it is more fun writing this than writing a report on the performance and aerodynamics of an MAV.

-For more amusing and less contrived definitions, look up my ones for France or Europe. They're OK.

Cullum

To Cullum a conversation is to deprive participants of any enjoyment they may have been feeling in the time leading up to the unwanted intrusion, which usually comes in the form of over-enthusiastic laughing followed by doubling over and, in extreme cases, knee slapping.

Cullum also refers to the practice of inviting oneself to social gatherings, having assumed that hearing when and where an event is occuring constitutes a valid invitation.
