When a LAD gets a girlfriend and happily settles into the nest that has been created.
A real NESTER would be James from this examle
When "James" is with "Zoe" they have stupid baby names for eachother such as "Bubsy"... NESTER LAD.
He was always having to talk to her even if he just left her... Nester LAD.
Arguments would be had over the girlfriend "Zoe" not being happy with the LAD "James" when he wanted to go out with the LADS... NESTER LAD
As you can see from examples..He (James) was deep into the nest.
