B's pizza?

So I gave out my phone number for the first time. We'll call him Mountain Dew. We had been emailing a bit but looking back, he didn't give much info or give indepth descriptions in his emails. But he asked a couple of times for my phone number and I gave in. An hour later I get a text, "I want to place an order for n extra large pepperoni....thanks :-)." I thought it was weird and reverse white paged the number (that's a verb, right?) and found out it was indeed Mountain Dew. Before I could come up with a response he said "is this b's pizza? ;-)" I just said, "Who is this?" and he said, "its Mt. Dew...how are u today." He seemed to think this was funny and now is surprised I didn't find it funny, but rather thought it was odd. And now he has my number. Great.
