There was a cohort of grad students living in university housing at a small institution of higher learning in the Greater Los Angeles area in the foothills of the San Gabriel Mountains who stayed up that late to watch a certain TV program because they all lacked a normal social life. This television program from Canada featured members of the Toronto Second City improvisational comic troupe, and this program was shown in Los Angeles following NBC Saturday Night Live. Several of the actors went on to appear on Saturday Night Live and later in movies. It is the shared culture of those grad students, and at least one of them, who happened to be from Canada, went on to contribute scientifically to astronomy.
This program, if you can believe it, was even more out-of-the-mainstream, subversive and edgy and not ready for prime time than the Saturday Night Live of the late 1970s. Toronto was a "second city" to the Canadian cultural center of Montreal, and Canadians I have known carry a resentment that Canada is a "second country" to the U.S., and the television program, originating in a fictitious "downmarket" generic North American city named "Melonville" built heavily on those themes.
One of the sketches was called Celebrity Blow-up, which parodied the sort of TV content that could be developed at a downmarket, North American TV station, featured a pair of actors dressed in denim coveralls who spoke ungrammatically. Their guests were other comics doing character impressions of well-known Hollywood actors who were known to over-act or otherwise have a high opinion of themselves as actors and be ripe for comedic parody. Each "guest" was encouraged to "blow up" on screen, where they literally exploded, which in turn was a cheesy video special effect within the budget of a downmarket TV station originating this fictitious TV program. Lacking cultural refinement, the denim-wearing hosts would find this entertaining and yell, "he blowed-up, real good!"
Your astronomer colleagues, who just might include my Canadian friend from over 40 years ago, are excited about the prospect that a nearby recurrent nova would "blowed-up, real good!", which is as realistic as an overacting Hollywood actor vanishing in an explosion on camera, but since you are from a time, a place and a different cohort of students in graduate school, one perhaps not reliant on watching a low-budget Canadian-import TV program as a shared cultural experience, the reference doesn't have any context, for which I apologize sincerely.
