This move is done after engaging in doggystyle secks. The man ejaculates into the woman's vagina. He then holds his hand like a cup underneath the semen (Jellyfish) filled vagina. With his other hand he grabs the woman's side and begins to tickle her. If done correctly it will cause a muscle contraction that forces the semen from the vagina into the cupped hand. When the woman turns to look back to see what is going on, that is when the male siezes the opportunity and hits her right in between the eyes with a Jellyfish Fastball.
That bitch was so pissed when I hit her with a sidearm Jellyfish Fastball!
