When you're having a conversation on snapchat and open a message too long after it's sent so you forget what the conversation was about.

A common phenomena (AKA The Frothies) experienced by surfers who have caught an epic wave, after which, they struggle to recall any events or specific details from that wave, such as maneuvers or sections. Related symptoms to Wave Amnesia include being stoked and having an intense sense of euphoria.
Surfer Guy 1: Dude, just had the sickest wave yo.
Surfer Guy 2: Oh yeah, what did you do?
Surfer Guy 1: Fuck, I don't even know man. I got Wave Amnesia.
Surfer Guy 2: Yo, haha.

Surfer Guy 2: Yo, haha.

this is a severe case of amnesia
it only occurs when someone cares to forget a minigolf experience. is a serious condition. anyone with this condition should be treated with extreme caution (and love in some cases)

Convenient forgetfullness when it's beneficial not to remember the truth. Often seen during jury trials when a witness is asked an embarassing question.
I work my tail off all year but when it comes time for my performace review the boss always seems to have selective amnesia. Mr Oswald, what were you doing in that book depository? Uh, I dont' remember.

when you go on vacation and have a miserable time, (a big family fight for instance), and about a week after it you can't remember the fight or anything bad that happened and start planning the next family outing talking about how fucking epic it will be to get all 6 brothers under one roof!!!
1) Jim to his bro. Dude, I can't believe our golf weekend turned into a UFC house and Bill lost 3 teeth and the hospital trip!!!
Bro to Jim- Dude wtf are you taking about!! that vacation was epic and I was looking forward to the trip to Vegas!!!
