First of all put your chars close to eachother ( the one who is going to buff and the one whos recieving the buff ).
Log on to the char you want to buff.
Make a macro with something like this ( or just Disconnect )
/sit
/lay
(copy paste this as many times availible )
then quickly log onto the buff char, and you will see that your recently DC'ed char is still there.
Now buff him!
When you log onto him you will have the buffz0rs
