I think it's the right place to ask. English is not my native, so while I'm able to understand a majority of puns I come acrossб this one puzzles me:
Omg, I'm such a slowpoke. It turned out to be simple. Got it right after pressing post button.
"pun skill", obviously.
I think Pun is a literary term which means playing with words by using Homonyms (It means each of two or more words having the same spelling or pronunciation but different meanings and origins) for example Fare & Fair.
