To add drama to a situation. It could be in a really boring place like Yates with your 'friends' when
something really uneventful happens or
maybe when you're online and your
ex starts talking to you all of a sudden.
*group of friends are sitting around a table and a waitress comes over to collect empty plates. Waitress struggles and almost drops the plates*
Waitress: WOAH.
OR.
*someone accidentily goes on facebook chat and clicks online to their '
people I
don't want to talk to' group.. 2 seconds later an
ex pops up typing your name in capitals*
Crazy ex: BOB!!
You: WOAH.
