A person who prevents another from having cybersex via unwelcomed words, actions or simply the sheer presence of being nearby.
I was about to hook up with BigVixen2742, and then littlepinocchio625 had to butt into the conversation with his views of how photon torpedos wouldn't be possible in a near-space atmosphere, and bam! BigVixen2742 suddenly logged out. I hate that cyberblocker littlepinocchio625! He always seems to do that to me.
