Making a sound with your guitar by either running your fingers or a pick across the strings - fingers on the opposite hand are usually making a chord formations - hence strumming a chord. Strumming patterns are different, but that is the best way I can think of to define strum.
haha. ok, normally you rest your palm or wrist in the bridge to play single notes, or unenthusiastic chords. when you strum however, you whole forearm moves with your picking, and your bridge shouldnt be touched, nor should any other part of your guitar besides the strings and arm rest. in some cases you strum without anything touching your guitar other than the strings, but thats usually just when your standing to play.
