Halloween is nearly here and I’m sooooooooooo excited!!!!!! I can hardly speak because I am sooooooooooooooooooooooooooooooooooooooooo excited, in fact I have ants in my pants.

I can dress up as a witch, cast some spells on Real Madrid football players, and go trick and treating.
Yes, have ants in your pants means: you are very, very, very excited about something.
