when you are hanging out/ dating someone and someone, normally related to you walks in and sees you doing something, you probably shouldn't be doing.
like cuddling with a boy that isn't supposed to be at your house when you are alone. and you are in a 'compromising position' and your dad just saw. or walking in on two people that are close to each other and seem to want to escape and make small talk at a quick moment.
dude, last night her mom walked in and saw us in compromising positions.
