To defriend someone on facebook on their birthday when you don't care to wish them a happy birthday.
"I just pulled a birthday defriend. He totally won't notice since he'll be so distracted by all the 'happy birthday!' comments posted on his wall."

One's 35th Birthday. At 35 years of age one meets the minimum age requirement to be president of the United States. This qualifies the 35th Birthday as a milestone and permits one to turn it up a notch and get buckwild, while maintaining a sense of regality.
It's your Presidential Birthday Dan. You're 35 now so, put your pants back on, stop acting so jackassy and finish those tequila shots..Mr President.

Doesn't matter what day her birthday is, a birthday whore sucks up the whole month and makes it her birthday. You begin celebrations on the first of the month and end the festivities 4 am (or whenever the bars close) the last day of the month.
