The art of sneaking out of a restaurant without paying, even though you have plenty of cash to cover. Usually done after bar close with a feeling of invincibility, followed with feelings of guilt the next morning.
May include anxiety over the possibility of being arrested over a Denny's Grand Slam Breakfast.
Real faint of heart will call back the restaurant with some lame excuse and proceed to drive back to the establishment with a 10 dollar bill clutched in their fist.
Denny's: Good Morning, Denny's!
Joey: Uh, hi. I was at your establishment last night and I got a call from a friend who was sick. He needed a ride to the hospital and wouldn't you know it, I forgot to pay!
Denny's: You don't say!
Joey: Yup, I will be there in 20 minutes with the $6.80. Good Bye.
Denny's: (After hanging up & speaking to manager) Last night's dine and dash will be in to pay in 20 minutes!
Legendary name of fictitious urban female. Started popping up after 2007 and has been referred to several times on popular radio morning shows. "Tagline associated with this word is 'the dash don't be slient' referring of course to the proper pronunciation of the word.
