I learn that 'diss' is a shortened version of "disrespect" Urban Dictionary: diss
For example, try to diss me, man.
What's the opposite of it?
I searched 'spect' as shorthand for 'respect'.
Nevertheless, it does not feel as strong and smart as 'diss'
Note:
'Diss' is a extremely popular in China as cyberspeak for joking with each other.

"dis". Bare respek. – Jodrell Feb 05 '18 at 14:31
