stream-jacking 

is when someone spams your Google+ stream with lengthy posts so you have to scroll like crazy for posts of your other followees.

Stream-jacking is performed by self-important people who enjoy smelling their own farts.
A stream jacker is highly probable an attention whore

Oh man, this fella is stream-jacking the crap out of my Google+.

I've had it with you and your attention seeking. So long, stream-jacker. (Pressing delete key)

Stream-jack your mama, bitch. (Pressing delete key)
