fleshback 

An engaging memory or series of memories of a particularly awesome sexual encounter which suddenly flood into a person's mind at a later date.Such memories can be of a sexual OR sensual nature or more usually both but always relate to memories of extreme pleasure rather than simply sex.Usually these fleshbacks will occur in the company of that same partner from the original sexual encounter due to the "trigger" effect of a subtle smile or glance or( if on the phone at the time ) a spoken word or even something as innocent as a pause in conversation where both people fall victim to the inherent sexual tension of the moment.A shorter definition would be "flash backs of the flesh".

"Oh babe...everytime you look at me that way I have fleshbacks to last year"

Fleshback 

When, in movies or tv shows, there is a flashback to a sex scene or a nude moment - any glimpse of flesh.

"Man that guy keeps thinking back to when he saw that girl's tits through the window."
"Yeah, total fleshback."

Falshback 

When something sparks a drunken memory, but the person telling the story tells it wrong and has to be corrected by someone sober enough to remember.

Brah 1: I got a ride home from one of the bartenders. She was hot.

Brah 2: Nope, you’re having another falshback. You drove yourself home, slid into the mailbox, and slept with some nasty older lady.

war flashbacks 

1. When something happens that reminds you of an embarrassing, difficult, or so-disturbing-that-you'll-never-be-able-to-unsee-it event in your life.

2. Actual flashbacks to actual battles. Can happen with PTSD.

Oh my god, that was the same position my parents used when I walked in on them as a kid. I'm having war flashbacks!

Don't you trigger a war flashback, son. I once killed a man!
