When you're trying to get it in with a lady, and it's suddenly time to go ( because your ride is here/ the place closes/ it's time for her to leave etc. ) and you end up never getting to do anything with her.
Girl: I so wanna fuck you right now!

You: oh baby, let's do it!

Girl: Oh shit my moms here to pick me up, I gotta go!

You: ...well...damn...

Your friend: Well shit dude, Id say you just got clockblocked!
