The Athens Trident is when three guys are laying side-by-side. The man in the middle is on his side. The man posterior to him eats his ass while the man anterior to him gives him head. This forms the shape of a trident.
Can be spotted trying to entrap people into eliciting the distribution of narcotics, and stalking small time suppliers of said commodities.
Trident: 'Excuse me, young man, do you happen to have any marijuana that I can purchase from you today?'
Supplier: 'Errmm... I don't know what you're talking about, sorry.'
{...makes a hasty getaway...}
Supplier's friend: How many bags did you move?
Supplier: Couldn't sell anything, the tridents were on to me with the quickness.'
