A salutation expanded as With Great Regard as opposed to R (Regards), BR (Best Regards) or WSR (With Slight Regards).
Used to close an email, letter, text msg or memo to someone you respect. Meant as a manner of respect, but could also be perceived as subservient.
Dear Xxx,
I acknowledge that your solution surpasses my own and will defer to you in this matter.
WGR,
Yyy
A term that can be applied to anyone boring, and therefore not exhibiting behaviour likely to gain them admiration or respect from their closest friends. Can also mean someone who rides wet goats in the literal sense.
