Get a insy mug for your brother-in-law Paul.
insy is the most incredible girl you will ever be lucky enough to meet. Kind, generous, incredibly intelligent, absolutely stunning (even though she says she isn't), and the perfect girlfriend.

Her smile could light up any room she happens to be in, and when you've touched her heart, she would do absolutely anything to make you happy.

If you're ever lucky enough to get a girl like insy, never ever let her go, and treat her well, because she will be the best thing that could ever happen to you.

One day, she will make an amazing mother, and a brilliant wife. For an alternative definition, see 'perfection'.

Term to describe when someone tries really hard but just cant get the job done.
Named after the semi-famous german Unreal Tournament player inSi.

It originates from the german Expression:
"inSi kann nix!!!" (which roughly means "inSi sucks!!!")

The 3 exclamation marks have to be used to put more emphasis on the message.
"Wow, koby failed to sink that Buzzer-Shot and the Lakers lost? He pulled a real inSi off right there."

"Honey, I know you tried your best and the potatos taste good,
but i think the meat is a bit of an inSi."
