Back in the day, I always wondered what that SQL thing was? And then I learned it was "Structured Query Language" Okay, so I though it was "S-Q-L". And then I had someone ask me if I knew sequel. I was like "What?". So I have called it "sequel" ever since.
So:
mySQL = "my sequel" (god, the last thing anyone wants to see is the second edition/followup of me)
MSSQL = "em es sequel"
however, I don't follow that with postgreSQL, just cuz it is funny-looking, so:
postgreSQL = "post-gresk-ull"
