Generally used in the presence of a stinky hippie so that one can refer to him/her without his/her taking notice.
Whoa dude, HINKY STIPPIE alert, 12:00. Take evasive action.
Translation: Stop my friend, I have taken note of a stenchful individual of unkempt manner directly ahead of us. We must alter our course with great haste in order to avoid this person.
