the trip that one takes to relax and unwind after committing a murder, serious manslaughter, or slaying. usually over 50 miles from scene of crime.
Example 1: When Tony Soprano asphyxiated Christopher Multisanti in season 6 of 'The Sopranos,' he took a slaycation to Vegas after the funeral as the Feds investigated the death and the family mourned.
Example 2: Notorious BIG raps about "laying up in Miami with Tamika and Tammy" after he leaves gangsters "in bloodshed" in revenge for their shooting three of his men in the song "You're Nobody Til Somebody Kills You."
"Incidents like this I take trips / Lay up in Miami with Tamika and Tammy / Some Creole C-O bitches I met on tour / Push a peach Legend Coupe, gold teeth galore / Told me meet em in the future later, they'll take me shopping
buy me lavender and fuschia Gators..."
(Shopping is a common activity in slaycations)
