To place an erect penis inbetween your partners (or your own depending on how flexible you are) feet, and to thrust in and out. Also used as a humerous insult.

the DIAMOND FOOTWANK is when a female wearing ankle socks and a short skirt (no knickers required) lies facing a male and shapes her legs like a diamond.she will then masturbate the erect penis with her feet whilst FLICKING HER BEAN. with the fantastic view the male party will see EJACULATION does not take long.
the DIAMOND FOOT WANK is best appreciated in PULIC PLACES such as car show rooms and motorway hard shoulders
