whoa whoa whoa what do we have here?

Abrupt interruption of friend(s) conversation to signify hot chick in the vicinity. It is typically used in unison with a slight head nod in the direction of said hottie. The interruption is KEY; regardless of how important the conversation is, all parties, male or female, must be inconvenienced enough to look before resuming conversation.

Extra "whoas" may be added for effect, up to five is customary and acceptable.
