Person 2: You are so Ghillie suiting on them just make sure you got the right suit on. You don't want your winter suit on in the summer you will stick out like a sore thumb.
Originating in Portland, Oregon from a group of high schoolers attempting to defy authority, casual suiting refers to the increasingly widespread act of wearing a business suit with casual accessories - be this tennis shoes, etc. This can apply to either someone who knowingly or unknowingly does this. Similar in stupidity to planking and owling.
