LGS
Last go syndrome.
The absolute need to make that last go on the girl you still like but perhaps shouldnt.

hits you especially hard when you have a magical moment with the girl and you feel like you've got a significant shot at a solid last go.
brenda and I hung out for like 5 hours on friday, LGS is commanding me to strike while the iron's hot!

dude, Ive got LGS so bad, everytime I see karen I just want to tell her I love her and she needs to give me another chance, I cant help myself!

if you dont get this LGS under control you're gonna end up dating a chick who dumped you in the eigth grade

dont be hasty. fend the LGS off a little longer and make a well-prepared last go. the timing just isnt right
