talking to the same person on both facebook and myspace at the same time.
friend (on myspace): "hey how are you?"
you (also on myspace): "good just on the computer."
then you switch over to facebook to check on things...
same friend (now on facebook): "hey, long time no talk. jk"
you (on facebook): "ha, i know. i do facespacing constantly."
and then you continue talking on both sites.
