We're young enough to say...

Once upon a time..

I bought an AC/DC shirt.

My dad, after seeing it, says the following:

"Hey I like your shirt!! Are you bisexual now?"

When I asked him what the heck he was talking about, he told me, "golookitupontheinternet"

So I did.

I guess ac-dc was slang for being bi.

True story.
