Sign language

People tend to like communicate in various ways. For example talk, sing, dance, showing expressions, eye signals and Sign Languages. Personally i think that sign language tend to be the best thing among other communications. Talking? Nah its old school. For people who cant hear properly they might not understand wtf are you talking about! But using sign language they can see clearly. Lets not talk about blind people they aren't related in this topic.
Various sign languages are available for us to use! As stated:

Happy~> Move both your hands together and clap
Emo~> Use both your hands and put on your chin.
Shocked~>Jump and raise both your hands high up.
Horny~>Move your eye brows up and down at some hot chick.
Rock~> Put your 1st 2 fingers up, next 2 down and the last one up.
Pissed~> Point the middle finger.

I favour pissed the middle finger the most and also known as the international language!
There was this day i was walking around the mall and i saw this really cute pen. It suits one of the emotions stated up there which was ROCK.

Rockkkk!!

This cute little pen says rock.
And there is the most anticipated international finger! When you're pissed, despite in any situation or when you're gonna get beaten up or something just show this.

Piss off.

Or maybe trying out the cuter version.
Hey sweetie piss off.

So whenever you dont like any particular teacher, just act like you're writing something and show it up right make sure she sees it and act innocent. But actually you're pointing at her without her noticing like this.Take this and piss off!

At the finger tip had a smile, so my finger smiled too.
