happy stroke

An event when you wheeze out in laughter and inhale back in so intensely that it resembles a stroke or a seizure.

Sam: *starts laughing insanely hard*
Pam: Oh my god, Sam! Are you okay?
Cam: Call an ambulance! Sam had a seizure!
Sam: *wheezes out* "No, it's a-" *wheezes* "happy stroke!"
