Love. Interchangeable for either the verb or the noun. Either for a playful replacement of the word to tease actually saying it, or when too nervous to come right out and say the word love.
"I know love is a strong word, but I'm saying it anyway!"
Because love is a strong word, and sometimes it's just easier to say strong word instead.
I strong word you.
Haha I strong word dirty jokes, I really do!
