If you use it right, Snapchat can be the ultimate flirting tool, and Irish model Holly Carpenter knows all the tricks. 

The brunette beauty, based in Dublin, put together a little Snapchat translation lesson for any men out there who might be fooled into thinking you're only "casually" sending him that picture of yourself looking absolutely stunning on a "single girls' night out."

Holly's blog post was first written back in April but over the last 24 hours it has gone viral worldwide, being shared everywhere from the US to New Zealand and beyond. And with good reason too, as some of her lessons are pretty damn hilarious.

There's the "aren't I just adorable?" puppy picture:

The cheeky bathtub shot:

The "oh, were my boobs on show?" selfie:

And, of course, the drunken Snapchat you NEVER intended to send:

We reckon Holly should look at a career change – this lady needs her own stand-up show!
