Hippy Barthday 

An ironic anagram of "Happy Birthday"; Hippies by stereotype don't have baths, & "Barth" is the stereotypical pronunciation "toffs"/rich folk make. Double serving of irony & a jestful way to wish Happy Birthday.

Hippy Barthday!

Happ-E Birthday 

A birthday wish when given in an electronic form, such as on a social networking website. In recent years happ-E birthdays have skyrocketed in popularity relative to face-to-face and telephonic birthday wishes because they require much less effort and can be given without having to awkwardly converse with the wish’s recipient or even remember their birthday. Unfortunately, happ-e birthdays are so easy to give that all 450 of your Facebook friends are obligated to post redundant messages on your wall on your birthday and if even one neglects to take part it constitutes a treacherous insult.

I logged on to Facebook this morning and saw that I had 7 happ-e birthdays to give so I called into my job and told them I’d be late.
