A Calvinist is typically used to describe anyone who holds to TULIP (Total Depravity, Unconditional Election, Limited Atonement, and Perseverance of the Saints). A Calvinist can be Baptist, Presbyterian, Plymouth Brethren, and even some Methodists.
Bro. Reformed,
What was said was for rhetorical effect that is all. Some use the terms and do not know what they mean. R.C. Sproul (I find myself quoting him a lot lately) said that theology had to be done on a razor blade's edge. So for those who do know the difference amongst the terms I am sure they will appreciate the help you and I have provided.
Thanks much for the clarification.
