Rubutu Joke gone wrong

Some time ago, I jokingly made a post on Facebook about rubutu. People who understood the motive took it in jest and laughed with me. Unknown to me was the fact that a brother following me on there had taken it seriously. We hadn’t met before, but he lived close to my place. On meeting me for the first time, the following ensued:

"Mallam, eyi no me p3 bi o," he said in a pitiful manner.
[Mallam, I want my fill of that thing.]

Confused, I asked "aba eyi?".
[What thing?]

He replied " eyi no aa dano 3de to Facebook no". [That thing you posted on Facebook.]

Wondering who he is and what he's hinting at, I probed further "ah, menyim wo wc hen? Eyi no onnyi dzin a?".
[Ah, where do I know you from? Does that thing bear no name?]

At this juncture, it was obvious that I was gradually losing my cool.

He came closer and murmured " wcfr3 me ... na me y3 wo ycnko wc Facebook. Last bi me hu d3 3se ay3 rubutu bi na mese ndz3mba pii rehaw me ntsi me so me p3 bi. Nanka me re ba wo fie mpo."
[I am...we're friends on Facebook. Some time ago, I read you'd prepared a certain rubutu and looking at how problematic a lot of things are for me, I believe I need some. I was even about coming to your house.]

A joke gone bad. I had to spend some time explaining to him how it was all a joke and why he seemed to have missed it.

Since that encounter, I'm never oblivious of adding a silver lining of caveat to jokes I believe are expensive.
