A beeriod is the passing of an awkward, uncomfortable and sometimes painful poo which occurs the day after a nights or days drinking!

This can happen all at once, or happens throughout the day, where one is said to be on their beeriod. It has many nicknames such as "having a black baby" or "burning the whole off myself"

It has many side affects such as:
Screaming
Scratching
Farting
Saying, "Hot, Hot, Hot"
Being irritable
Stomach cramps
Increase in waist size
Very smelly shits
And being fidgety

Guinness one of the leading factors of a beeriod, is so heavy that beeriod symptoms happen almost immediately! Since the smoking ban in Ireland, this has proved quite a difficult problem as pubs are becoming more potent in the flavour of beeriodosity, a gas more dangerous than tobacco!
Example 1:
Guy #1: Hey where are you going?
Guy #2: Oh man I gotta take a beeriod.
Guy #1: Oh fuck, I am staying well away from that toilet!
(20 minutes later)
Guy #3: Jesus Christ, who just had their Beeriod?!

Example 2:
Girl: Ugh, what is that smell?
Guy: Sorry babe, I'm on my beeriod.
