A longman is typically an individual who chooses to elongate a particular task for the purposes of irritation or general ignorance of surroundings. This keeps with a popular emerging British tradition to add man or similar as a suffix to a regular verb to form a compound word such as 'fuckboy, wasteman, roadman'.

In Lehman's terms a longman is a man/women who takes overly long at any given situation with total disregard for responsibility.

Get a Longman mug for your friend Julia.
1) What the missionary position is called in Cockermouth, England.

2) When you put your dick in her mouth and finger her at the same time.
I went to Cockermouth and laid this british freak on her back and gave her The Longman Swallow!

She loves The Longman Swallow.
