relative humidity

The bead of sweat that rolls down your Sister's back when you're banging her doggie style.

The Relative Humidity was high during our Family Union

realitician

An individual (usually working in a call center) who understands people only know what they are told. Consequently reality is controlled.

The realitician knows that despite the fact he failed to enter the customer's PO yesterday he can put it up today and blame the order entry system (or shipping, or the fax machine...).

relatives

Parasites that live in your house that no matter how much poison you put in the pot roast they still wont die.

Why are your relatives crapping themselves?

relative

A way of saying cousin without actually saying it. So if your a blood, and you don't want to say cousin or cuz, you say relative.

Whats goin' on relative?

Explosive reactive armour

Initially designed to strengthen tanks, a reactive armour, that explodes when hit by either kinetic energy or high explosive antitank (HEAT) projectiles, disrupting the round, and degrading its penetration. Explosive reactive armour is most effective against HEAT rounds.

The new Russian Kontakt-5 ERA is not completely destroyed when hit - it still functions as armour after exploding.

Anti-tank weapons work by piercing the armour and exploding inside, thus killing the crew.

Explosive reactive armour counteracts the force of the explosion by creating another explosion on itself. Against shaped charged missiles, this type of armour really comes into it's own.

The design was patented by Manfred Held in the 1970's.

ERA will save the lives of the crew and allow the tank to fight another day.

relative humidity

It's that little drop of sweat that beads up on the back of your neck and dribbles down your back, thru your crack and eventually drips off of your ball while your fucking you sister.
