A lot like a flashback, but the memory that's pulled up is a heavily romanticized version of what actually happened. Usually involves two males and occurs most often in the twisted minds of yaoi fangirls.
Flashback:
Guy 1: Hey man, you all right?
Guy 2: Yeah, I'm fine. Thanks.
Slashback:
Guy 1: Darling! Are you hurt?
Guy 2: I'll be fine now that I'm in your arms, my love!
Derived from the root word sloshed. Occurs when one drinks enough alcohol to surpass the point of being sloshed and experiences an elevated level of drunkenness. Those experiencing this state may experience one of the following side effects: start repeating jokes, demanding celeb shots in pong, and might attempt to flip cutlery in the kitchen, or challenging any/all partygoers to shotgun race.
