Person 2: Hell yea my birthdays this month!
Person 1: IKR?! mine too.
Person 2: who doesnt love January?
Person 1: only losers :p
Usually the person being januaried will try very hard to figure out what the person meant, making them look like a complete and utter idiot, as they meant nothing. Added people who are in on the january will add to the hilarity.
Person 1: Yo, what month comes after June?
Person 2: July?
1: Are Julying to me?
2: Ha ha ha very funny.
1: Ok listen to this one: What month comes after December?
1: Are you Januarying to me? *Everone "in" on the joke starts laughing*
2: (Embarrassed) What? I don't get it. What do you mean?
When someone is found out:
Person 1: Dude I brought home like 20 chicks last night man!
Person 2: Yeah right, you're januarying me...
Person 1: Damn you got me.
January - Time of Sorrows, Limbo season, Out of the light and into the gloom, Month of the Eskimo, Month of Despair, Time of total submission.
(it is as far away from all the fun months as Monday is from the fun days. Like July - the Saturday of the year, or December - the Sunday of the year).
