Years ago I worked on a project where a lot of the code was done in Tcl (pronounced "tickle"). Management would not say "tickle", instead they insisted on saying T-C-L. Tcl is a pretty neat language, and while I was on the project, I couldn't help but wonder how much it's name had held it back.
I call it 'T-C-L' despite being a programmer, because calling it 'tickle' just sounds stupid to me. 'Sequel' for 'SQL' similarly sounds weird so I just say 'S-Q-L'.
