look up any word, like hipster:
 
1.
A hand motion that is used in a situation when someone has made a comment inappropriate to the setting or conversation. Its usage is similar to awkward turtle, and it is comprised of a hand raised so that the elbow, shoulder and wrist form 90 degree angles and the palm faces downward.
In a classroom:
Person 1: There are a lot of homosexuals there.
Person 2: Um...
Person 3 raises hand to make the inappropriate giraffe.

In a conversation:
Person 1 makes a lewd comment or gesture.
Person 2 makes inappropriate giraffe.
