Flamstalgia

When someone hates a new or old installment of a series. Even if the newer/older version is superior in every way, one who has Flamstalgia will find something to complain about, and say how it doesn't compare to the version they played and loved originally.

Veteran Player: I am tired of this Modern Warfare 3 nonsense, COD 4 was the shit man.
New Player: No man Modern Warfare 3 is the king of COD, it doesn't suck. I tried COD 4, it is terrible.
Non Player: They are both very similar and you guys just have Flamstalgia.

Flap Cracker 

When a lady squirts some love paste onto a cracker for her guy/gals eating pleasure.

Please note: When making you own flap crackers be sure to eat on the day of creation due to a short BBE date, they can quickly turn nasty!
