This is a two part question.

1.) When spelling out a word in kana, what is the correct way to call the small つ (for example the small っ in ちっちゃい)?

I only have experience with my Japanese friends using the informal sounding




Is there a formal grammatical term for this "character"?

2.) If there is, but in reality it sounds too academic, which term would be the most immediately understandable in an informal setting?

    It isn't the name for the character, but I often use 促音{そくおん} to refer to it, since that's what its function is. May 11 '13 at 19:15

It appears that one more-formal way to describe characters like 「っ」 is to use the phrase 「小書{こが}き」文字{もじ} or simply「小書{こが}き」。 So, in the case of 「っ」, it would be something like: 小書{こが}きの「つ」.

But in an informal context, something like「小さい『つ』」would probably get the point across.

For more information, there is a more detailed writeup by a user named "nullstrings27" that further explains 小書{こが}き文字{もじ} in general.
