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.

Lentilist

Lentilist is a derogatory term for anyone with anti-car, anti-progress, anti-capitalist views. It particularly applies to filthy, scummy layabouts who spend their time protesting outside power stations instead of getting a fucking job, or middle-class socialist wankers with a guilt complex.

The term is derived from the assumption that people of this kind would rather eat lentils than a big juicy steak.

Also see: sandalist, yoghut weaver

Jane: "Oh, you shoud cycle to work, it's soooo much better for the environment"
Bob: "Fuck off you lentilist"

lenlen

A cute girl with great looks. Asian and short who loves long hair and has a cute smile and crazy eyebrows. A freaky girl (sex) that can’t seem to resist. Has the craziest laugh and never seems to shy away from danger. Always wants a fun time and has crazy friends of all kinds. She loves turtles and grew up in the tropic islands and has a fun lifestyle that never ends. Lenlen is a very loving and friendly person
