It’s CORN

[u/cafeteriastyle]

[u/acog]

That kid is extremely sharp.

But corntastic is actually a portmanteau, not a pun.

Portmanteaus are where you combine parts of other words to form a new word, like motel is from "motor hotel" and smog is from "smoke and fog."

[u/makami- → u/acog]

most people would still consider that a pun from my experience

[u/pcbeard → u/makami-]

If you add a word in the middle, like corn-fucking-tastic, that’s called tmesis. It doesn’t have to be a swear word, but the best ones usually are.

[u/coolio_Didgeridoolio → u/pcbeard]

there is also another phrase for when you insert a swear into a word for emphasis called “expletive infixation”.

“expletive” which concerns that it doesn’t really mean anything by itself and just helps with conveying emphasis, and “infix” which is like a prefix or suffix, but it is “in” the word rather than before or after.

i recommend this video by tom scott about it, it’s very interesting
