To 'step on a joke' is a term in comedy writing. It means to ruin a decent joke by by following it too quickly with a riff or another punchline in an attempt to draw more laughs. Stepping on a joke is a fatal flaw of bad sitcoms and improv groups, where several actors may step on each other's jokes in attempts to one-up each other.
Joke-stepping is particularly noticeable in certain comics, where attempts to cram several related punchlines into a shortspace such as a final panel are more obvious than in filmed media.
In some usage, to step on a joke means to ruin it by deflating it or explaining it. This is more accurately called 'killing the joke' which can be a deliberate form of anti-humor. Stepping on the joke usually isn't.
To use the phrase:
Did you see that Jay Leno monologue? Making all those lame comments after his punchline? He stepped on that joke so hard he practically curb-stomped it.
To step on the joke:
It was like he was going, "Kiss the curb, you joke!" Heh. Hmm. Yeah. Whoo.
A term that came from Spongebob Squarepants. It means to be walking while singing "steppin on the beat" and add your own toon, and step oddly on each beat of your toon
Spongebob- "STEPPIN ON THE BEAT DO DO DO DO! STEPPIN ON THE BEAT DO DO DO DO! STEPPIN ON THE BEAT DO DO DO DO! STEPPIN ON THE BEAT LEEDLEE DEE DO!"
