When someone is being annoying, giving you dirty looks or is simply being rude for no reason, you call them 'eggy'.
Teacher: *says assignment*
Me: what do we have to do?
Matilda: ugh Zoe you should've listened
Me: can you stop being so eggy
Me: Lillian I really like your jumper where is it from?
Lillian: Zoe it's sold out you're never going to get it so don't even try.
Me: Why are you so eggy?
