The anti-static bag that an I.T. professional keeps his extra sticks of RAM in.
"Hey, pass me your rambag, this machine only has 128MB of RAM and it's running Windows Vista."
The act of John Rambo embarking on what typically is known as a rampage. However, that definition only applies to everyone who is not John Rambo. If this ultimate male specimen ever decides to "rampage," the condition is then upgraded to a "Rambage."
<Dude1> Did you see that Rambage? It was sooooo much better than that other guy's rampage.
<Dude2> Dude, that's because he's Rambo. Only Rambo could do that.
