Certain sexual procedure only found in obscene circles. It involves getting a girl (or a guy i guess) getting them to open their mouth fully and then clingfilming the top. You then procede to poke the cling film in a little. Followed by turding on the clingfilm. You then follow up with ejaculating on the turd, and finally poking the "full english" into her/his mouth
Jesus, that bird just ate a full english, she is my kind of girl!
