F punching is where your girl is laying/sitting down with their legs spread,while your girl is tricked thinking your about to finger her you go full force with a punch and scream"FALCOOO PUUUUNCH"
Friend:Hey what did you do to your girlfriend yesterday?

Guy:Oh instead of fingering her I gave her a "F punch".

Friend: so how did she react?

Guy:She left me.....
