Casually sneaking things that you're craving while on your period like:

Me: *grabbing chips*
Mom: Honey could you—
Me: *swallows six chips whole and chucks bag of chips*
Mom: *walks into kitchen*
Me: Sorry, what?
Mom: ...what are you doing?
Me: Uh
Mom: You're not sneaking something, are you?
Me: -___- Do I look that stupid?
Mom: Why is there a bag of chips on the ground?
Me: ...
Mom: Rawr
Me: YOU SAW NOTHING
Mom: ...
Me: *jazz dances my way out of the kitchen*
