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:
Saying, "Hot, Hot, Hot"
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!

Guy #3: Jesus Christ, who just had their Beeriod?!
Girl: Ugh, what is that smell?
Guy: Sorry babe, I'm on my beeriod.
Man 2: This is your fifth pint; don't you think you've had enough.
Man 1: Usually, but it's my wife's time of the month, so I'm on my Beeriod
Man 2: Oh shit! This one's on the house man!
Me: yea, dude. Looks like we synced up our beeriod. (High five)
The odour released when having ones beeriod is potent and unpleasant, to avoid side effects such as regurgitation or gagging, it is advisable to carry a can of air-freshener for the duration of the beeriod to use at ones discretion. It is customary to inform ones flatmates that one has had ones beeriod so they too can avoid the fallout.
