Virtual Hangover
When you wake up the next morning regretting what you did online last night.
OMG I've got a virtual hangover. What did I do online last night,shit I signed up to a virtual data centre, my girl friend will kill me and I won't be able to afford to eat for a month.

Shit, what did I do online last night? I signed up to a dating site and invited a Russian girl around my flat and payed for the flights, now I'm broke.
