The final level of keyboard smashing. You did all of the letter combinations then you did all caps as well then you did all of that backward. Its so long that Urban Dictionary doesn't let you add the last `. I don't think there is anything further than this unless you add spaces.
You are so bored that you typed in every character top to bottom then again using SHIFT then left to right and again using SHIFT.
You cant use this in a sentence. It's physically impossible and implausible. But here's a sentence anyway. "`1qaz2wsx3edc4rfv5tgb6yhn7ujm8ik,9ol.0p;/-'=\~!QAZ@WSX#EDC$RFV%TGB^YHN&UJM*IK<(OL>)P:?_{"+}|`1234567890-=qwertyuiop\asdfghjkl;'zxcvbnm,./~!@#$%^&*()_+QWERTYUIOP{}|ASDFGHJKL:"ZXCVBNM<>?" You say. "What the fuck". That's the sentence.

You are so bored you hit every key on the keyboard forwards and diagonal lower and uppercase.
"Hey bro! Look up `1234567890-=qwertyuiop\asdfghjkl;'zxcvbnm,./`1qaz2wsx3edc4rfv5tgb6yhn7ujm8ik,9ol.0p;/-'=\~!@#$%^&*()_+QWERTYUIOP{}|ASDFGHJKL:"ZXCVBNM<>?~!QAZ@WSX#EDC$RFV%TGB^YHN&UJM*IK<(OL>)P:?_{"+}!"
