Given by Terri Edda Miller as her definition of Castle Season 6 or more appropriately called SEASON SEX. Basically Castle + Orgasm = Castlegasm. It's an immediate after effect of Castle & Beckett's "Crime Solving Foreply" & "Eyesex".
Another name for Nashville. Called this because Nashville is the center for glitz and glamour, stealing all the spotlight from dumpy Memphis, and a GREAT place to live.
The excitedness that overwhelms you when looking at or feeling a certain sum of money. More commonly acheived from the stroking of a money clip full of nice Benjamin Franklin $100 bills.
Dude 1-"I got my paycheck the other day and boy am i excited to get a nice cashgasm with Benjamin."
Guy 2-"Is Benjamin good at giving you this cashgasm?"
Dude 3-"He's the greatest. The best part is there is no mess to clean up either."
