When you can see your gonna regret something that your gonna proceed in doing anyway.
"Man in future retrospect i should have worn a condom" in reference to seeing a squaddie mattress your about to chat up and bone.

In telling your friend over the phone you dont appeaciate the lack of support he gave over the non condom incident: "dude in future retrospect i should have slapped you harder"(next time you see him give him a slap thus confirming your future retrospect)
