This is the fucking letter Y, are you honestly THAT bored!? Like holy shit dude you got to be bored out of your mind to search "Y". Or you didn't search "Y", Or you're an idiot.
Can be interpreted into two meanings.
1: A short of "Why". Seriously, it's a short word. Are you that lazy?
2: Short form of "Yes". This Y form is uncommon and mostly used in countries such as Indonesia.
