When someone mimes jerking off (
male masturbation) in order to signify one of the following.
1.
Boredom during a conversation.
2. Annoyance at what is being said by someone.
3. To symbolically show that what is going on is pointless, and/or masturbatory.
Often accompanied by rolling your eyes.
For Example:
1. Speaking on the
phone with someone who doesn't know when to shut up, so you do the jerk off gesture.
2. Someone is saying something you think is stupid so you do the jerk off gesture to show what you think of them.
3. Someone is pontificating on a subject you find stupid or pointless, with a great
air of pomposity and pretense, so you do the jerk off gesture to show what you think of how they are using their
time.
Alternately you
may also consider the topic important, but find the delivery of said speech to be extremely self indulgent. IE, someone more interested in propping them self up than dealing with the subject at
hand.
"So I was listening to this professor talk about the battle of the bulge and I love war
history, but the dude
just kept on and on, like he wouldn't shut up. I was doing the jerk off gesture under the
table half the lecture."
