Greetings! D’ B I D A T Brood cordially invites you to attend their BBQ session. It is worthwhile to "horse around", you know... Our mission is to "shoot off one’s mouth", by making a "tongue-in-cheek" remark, lah. Well, we are not trying to "pull someone’s leg" or "drive someone up a wall" or "string someone along". Indeed, we try to get rid of such "wet blanket". Please come over for the BBQ, as we are trying to "knock someone’s socks off"!
Is it too hard to understand the words? Well, it’s American English Idioms. Search for it through the Internet. Good luck buddies!
