Don't know what this means?

When me and my boyfriend make love, he says really weird things. An example of what he said a few weeks ago was: "The cold may do the love". Another was "Please keep the ice berg in the lamp". I really don't know what any of this means, and when I ask my boyfriend about it he denies saying anyting. I know that he is though, so can anyone help me figure out what this all means?
