A positive way to brag about being a decent person.
"You're the most Jesusly man I've ever known"
"Out of nowhere that eagle landed and stopped the laser guided missile, how very Jesusly of it"
The word is used in place of words such as 'amazing', 'awesome', 'great' or 'cool'. Anything and everything good in life, is jesusly.
Merman B: Yeah, it was jesusly!
