To let someone know they are full of crap or that you just don't care by making a jerking off motion with your hand.
Before the Partwii, Lauren, the cyborg, bus surfed over to Mickey D’s with his brofriend Chuck Norris and bought a McGangbang happy meal with the funds that he jacked from his sugar momma after his disco nap that afternoon. Chuck pulled out his phone from his nuthuggers and started sexting a ginger slice with a tramp stamp that he had been friendly following ever since they shared a game of Jager pong. Lauren gave Chuck the air jerk as he noticed Tanasa the grade digger that sat next to him in his art class. Lauren gave her the “let’s just be friends” nod and grabbed his happy meal. As Lauren walked outside he saw, Bruce, the designated drunk, as he started wailing teenybopper show tunes. Bruce was manstrating again and wanted his fix of Dr. Pepper and Big league chew. The night of celebrating Lauren’s nomotion had barely even started and already he was knackered.

Making a 'jerking off' motion with one's hand to express disgust, disinterest or disbelief, while simulatenously rolling one's eyes. Similar to concept of playing air guitar.
I think she's pissed. She just gave me an air jerk and walked away.

A motion done with the hand simulating
masturbation. Instead of just conveying an
opinion of someone, it can also be used to convey
to a friend or co-worker what a complete and
utter waste of time something is (or was).
Joe: So how do feel about spending two days

preparing for a meeting and then it's cancelled?

Moe: (simultaneously rolls eyes, makes a wry face

and performs the air jerk)
