My colleague unknowingly uses the word "paralyze" for "parallelize". When is the good time to correctly him? So far he has successfully paralyzed my code.

*correct, not correctly

Oh, the irony! But it cracked me though.

Bro. My university one time used "univercity" for university (student mistake) XD

My friends told me i had been saying future when i meant feature for years. They had a good laugh and i still feel like an idiot, but it's better to actually know instead of looking like an idiot.
So tell him. he'll get over it and be thankful
