I understand what you wrote but it's chapurreado. Here's a better way of saying it keeping as many words you originally chose as I could:
I am tempted to link todays daily word leche to Jane's post about
el colmo.
Consider the following two phrases:

Es la leche
Es el colmo

They mean the same, but the former is vulgar and the latter isn't.
Are both terms used in other Spanish-speaking countries?
(You could also say"they both mean the same with the former being
vulgar and the latter no vulgar at all)

Other words for colmo in English:
The final word in elegance. can you use la ultima palabra en elegancia?
The very model of ...
The paradigm of ... (not often used)
