With what do you Interlard your conversations?

Interlard, the Word of the Day for Thursday, April 8, 2010, is almost self-explanatory in its basest meaning. The original sense of the word, now obsolete, was "to place lard or bacon amongst, or to mix, as fat meat with lean." Now, however it means, “to insert between; to mix or mingle; especially, to introduce something foreign or irrelevant into; as, "to interlard a conversation with oaths or allusions."
I was especially taken by the words “to introduce something foreign or irrelevant into” and the example of "to interlard a conversation with oaths or allusions." How many time’s have you experienced a good conversation ruined by the introduction of foreign or irrelevant thoughts and words? And the more so, by totally unnecessary swear words; and oft, even more so, by the inexcusable and offensive to me at least, word, “Umm!”
Of course it is always very easy to pick on the conversation of others isn’t it? Bu but let us also never forget our own conversations too! Yes, how many foreign or irrelevant words, (like oaths or allusions), do we use each day? So let this word of the day become real to us all and if we must interlard our conversations, please let us do it with relevant and meaningful words and not offensive or dumb ones. BFNW
