(Slang)When a woman becomes sexually arroused and secretes lubrication from her vagina so that she is ready for intercourse. i.e. 'To get wet'. However, this term is slighty stronger, and suggests that she is so arroused, she is at the point of flooding!
Ooh, I was SOOO arroused last night during Emmerdale by that Patsy, I was as wet as an otter!!
James:- Percy! I've got a new term for you!
Percy:- Go on!!
James:- Wet as an otter!!
Percy:- He he he dude, that's gross! That would put most people off sex for life!! What does it mean you sick little monkey?
James:- To get wet!!!
