Act the fool

This quote is similar to Ludacris' song "Act a fool", from 2Fast2Furious, which means "acting like a fool, in a desperate way" aka "last resort, trump card". However, this one means "act like a fool, while you're smarter than everyone else". Or in other words, "Trolling 101". It may be similar in some situations.... =)

"Act the fool" also means, in some countries, "fazer-se de parvo".

Crowd: "haha, that guy is such a tool! Let's make fun of him!!"
Guy 1: (thinking w/ a grin) "hehe.... they think I'm a fool. I'll show them!"
Guy 2: "Yeah man.... Act the fool..." (thumbs up)

SYS

SYS = Sucking YourSelf

Some men have the amazing ability to suck his own cock! Also, some women have the skill to lick/suck her own vagina...

Wife: "I'm sick of you... Go suck yourself!"
Husband: "Gladly! I do it better than you anyway... I have my own SYStem."

Girl 1: "I won't lick your pussy..."
Girl 2: "God... I'll do it myself! Thank god for SYS..."

Boy 1: "Wow, dude.... you can do auto-fellatio? That's amazing!"
Boy 2: "......." Looks at Boy 1, smiles and thinks: "SYS rocks..."
