When a guy asks this question...

He's hoping to **** ya.

That's it - that's all.

If the guy is Irish, of course

Irish are known for a quick firey temper. so this expression is an inquiry of your temperament

Nope. If it a standard stupid pick-up line. A cliche, particularly on St. Patrick's Day.

Man: do you have a little Irish in you?
Woman: well no....
Man: Would you like to?

It is literally a solitication for sex. (If I told you you had a beautiful body ... )

hate to be a burst your ego but I am right

Not this time.

nope

it's a standard, supercheesy, pick-up line

I didn't think it was possible for my ego to get any bigger.... but somehow you did it.

No, he’s right bunny

It’s a cheesy pickup line but as max said it is exactly how it’s been told to countless eye rolling women.

I remember the first time it was used on me, and it didn’t get any better over the years.

I felt foolish the first time because I had fair skin and freckles. I thought the guy was actually asking a serious question and I basically replied not all people with freckles are Irish. Then he gave me a leer and asked if I wanted to (have a little Irish in me)

What an asshat, along with all other men that think that’s clever.

Yeah, right.

Just tell him "your Irish is not enough to be worth it" because all he wants to put in you is his Irish willy.

LOL!! Of all the garbage I've heard, this is a new one on me.
