Well one of the stupidest ones I have ever heard is:
"Baby, I lost my number, Can i have yours"..Heck No, search for your number else, sweetie....
"If I could rearrange the letter of the alphabets, I would put U and I together"....Yeah good luck with that...
Guys need to stop being so cheesy...and fake
And you ladies need to stop fronting even when you need us guys... Tell the truth you like it when we come to you
