A sex act involving three people, 2 males and 1 girl. First one man lays on his back with an erect penis. A girl then lays on top with the erect penis inside her anus or vagina, doesn't matter. Then a second man will get on top of the girl and insert his erect penis into an available hole (vagina, anus, doesn't matter).
much like getting screwed over or "owned", the term dicked refers to the porn act of some poor lass (or lad i guess) copping a shot in the eye (the worst of insults i beleive). The term though has many variations.
The "silent dicking" can be displayed soley by pointing to your open eye. this implies to those around you that you have just "copped one in the eye" or been "dicked" to some degree.
For a complete display of being dicked you can join the pointing of the eye with an out loud "man, i just got DICKED"
A friend sees another friend put down the phone across the office. The friends make eye contact, with friend A pointing towards his eye with a sad look on his face.
Friend B now knows friend A has copped a dicking.
Verbal dicking: "far out man, i just got dicked over at work for that promotion."
