Jeffed Up, or JEFFED is what happens when the "company" insists on providing sexual gratification, (usually via the anal fuck) (whether the recipient expects/desires it or not), followed up by a good serving of Boston Pancakes. To be "Jeffed Up", you may be "gratified" by any member or non-members (ie: dildo) of the Jeffing parties body. It is important to note that the "Jeffin" party usually follows this up with some type of fucking over, ie: a good cold bitchslap to the face of the Jeffed one. This may be ordered "Stat" as well, meaning it should be done ASAP. Believed to originate around the time of the revolutionary war in Boston, or Philadelphia.

Means the same as effing (fucking), but has 'jeffing' on the end, for no other reason than it rhyming rather well.

Existing briefly in ancient 2nd century Spanish territories, the term "Jef' Fmáine" refers to a sacred string of numbers reading "81, 76, 567, 462." These numbers were originally found on a stone tablet in 126 B.C. and were applied to anything from calculation tables to lattitude and longitude markings.
"Hey, i added 4,088,283,731 and 4,088,283,731 and got 8,176,567,462." "That sounds like an ancient spanish term "Jef' Fmáine."
