1.) A simple word to describe the immense attractiveness of a member of the opposite sex.

2.) A continuation from the above definition, used to describe the immense attractiveness of a situation/event.

It is derived from the popular game show hosted by Paddy McGuiness, Take Me Out, in which Paddy had the catchphrase of "no likey, no lightey!"

"No lightey" can also be used to describe the opposite of the above definitions.

All variations must be said in a Lancashire accent, optimally a Bolton accent, as in the style of Paddy himself.

lightey means that to be great.
