If someone is 'Jonesing', they are incredibly excited for something, sometimes to the point that the wait for this thing is getting on their tits.
'I'm Jonesing (Jones-ing) for this bag of sniff'
'I'm definitely not Jonesing (Jones-ing) for this prostate exam'
A deep desire to be someone else. A neighbor who has more or anyone and anything that you perceive to be better. The grass is greener syndrome.
They just bought a new Mustang and I am jonesing to the Jones right now.
