Get the Flirt Hand mug.
Using a friend (preferably the same gender) of someone you're interested in to get the information you want, i.e. sexual orientation, relationship status, social media.
I want to know if Jessica is seeing someone. How do I find out without being awkward or putting her on the spot if she is?

Try second-hand flirting bro. Ask her best friend Mackenzie; she'll know.
