Narrative:
Aircraft had a little residual ice on the outboard leading edge and needed de-icing. The first officer and I agreed on de-ice only as the weather was becoming partly cloudy. When [de-ice crew] came on the frequency I asked for 'de-ice only'; yet [de-ice crew] replied that they understood we wanted only a one step then. I corrected them and repeated my request for 'de-ice only'. After some confusing back and forth; we finally all agreed and got what we wanted. This report seems to become my annual 'no one here has a clue about de-icing.' case in point: I had to explain to my x-year first officer the difference between de-ice only; one-step and two-step. Even he did not know or understand what one-step is. Even though the verbiage in the fom and on the laminated cockpit cards has vastly improved; I believe there exists still way too much confusion and lack of knowledge on the three different ways we de-ice here. Being [cold weather] based; one would be surprised what exotic request one hears on the [de-ice crew] frequency; from both sides; even when we spell out what needs to be said verbatim to avoid potentially dangerous misunderstandings and to have everyone involved to have that shared mental model.

Title: B737 Captain reported deice terminology confusion.
Narrative: Aircraft had a little residual ice on the outboard leading edge and needed de-icing. The F/O and I agreed on de-ice only as the weather was becoming partly cloudy. When [de-ice crew] came on the frequency I asked for 'de-ice only'; yet [de-ice crew] replied that they understood we wanted only a one step then. I corrected them and repeated my request for 'de-ice only'. After some confusing back and forth; we finally all agreed and got what we wanted. This report seems to become my annual 'no one here has a clue about de-icing.' Case in point: I had to explain to my X-year F/O the difference between de-ice only; one-step and two-step. Even he did not know or understand what one-step is. Even though the verbiage in the FOM and on the laminated cockpit cards has vastly improved; I believe there exists still way too much confusion and lack of knowledge on the three different ways we de-ice here. Being [cold weather] based; one would be surprised what exotic request one hears on the [de-ice crew] frequency; from both sides; even when we spell out what needs to be said verbatim to avoid potentially dangerous misunderstandings and to have everyone involved to have that shared mental model.
