Verb. When a man strikes his erectpenis repeatedly onto a woman's vagina, focusing his strikes on her clitoris. Also known as, "clubbing the baby seal."
Clubbing the seal should only be performed during intimate moments and with the lights on. The woman must be supine with legs fully spread and the man must be kneeling, between her legs. The man should not be too portly. The penis must be fully erect and the labia should be spread open, usually with the assistance of the woman's fingers.
A variation of the phrase 'breaking the seal' whereby one often has to go to the toilet frequently when drinking, once they have gone for the first time of the evening. However, this version can have a variety of misunderstandings that sound like one is about to commit/has just committed an animal rights abuse.
Used mostly in parts of Lancashire and Cumbria, and in particular Lancaster.
Where have you been?' 'I have just been clubbing the seal'
