Well, I saw it in Buuhan1's avatar, but that's barely the beginning of it. This phrase is one that represents procrastination and vagueness at its best. Example:
A: "I'm gonna lose weight. For real this time."
B: "Well just when do you plan to do that?"
A: "After the holidays"
A: "WHEN WILL THE @#$% fillers end?!"
B: "Oh, some time after the holidays
The point is, from Thanksgiving in November to New Years Eve there are 3 major holidays. To take it a step further, it could last till the end of February, if you include MLK Jr.'s birthday, Groundhog day, Valentines day, Lincoln's birthday, etc.. To say you'll do something "After the holidays" is the biggest cop out of an answer ever. This phrase annoys the crap out of me because it really doesn't mean anything. Just thought I'd share. <3
