Due to their addled, shifty nature and incoherent mode of speech, the only two known methods of differentiating between sober and inebriated jaikies are a) a measuring the diameter of the pupil and b) measuring strength of the piss smell emanating from the individual's filthy shell-suit bottoms.
The term jaikie derives from Frosty Jacks, an extremely cheap white-cider-cum-paintstripper sold in local off-licenses, and popular among less salubrious individuals as a more inexpensive alternative to the ubiquitous Buckfast.
Can also be used as an adjective.
Female jaikie: "Hey pal, I know ye're an ugly basturt but I'll give ye a hand job if you buy me a bag o' chips!"
Human being: "You're no oil painting yourself, you fucking jaikie bitch! I'd rather put my willy in the hand of Dr No than in your jaikie, fag-stained claws. Now, jog on."
