look up any word, like donkey punch:
 
1.
Phonangulate verb

the act of two or more people using cellphones to either find each other verbally or by texting in an unfamiliar location.

I'll phonangulate you once I get to the Convention Center.
You arrange to meet someone in a large building or park but can not give a precise area because neither of you are familiar with the location. Once you both arrive you call each other or text each other saying...for example "I am by the merrygoround in the park . Or "I am at the bar on the 3rd floor of the hotel." You both PHONANGULATE until you meet face to face. The word is made up of triangulate..as in Triangulating a position and phone.

You did not know where to meet until one or both get to the location to get the lay of the land
