Australian cricketers back in back in the 80's / 90's were great with sledging the opposition batsmen with lines like ,"I fucked your mother last night " or" your wife gave good head last night" usually got the bloke out in the next few balls.
Rod Marsh & Ian Botham:
When Botham took guard in an Ashes match, Marsh welcomed him to the wicket with the immortal words: "So how's your wife & my kids?"
Botham retort was "Wife is fine, kids are retarded"
Glenn McGrath (bowling to portly Zimbabwean chicken farmer Eddo Brandes):
"Hey Eddo, why are you so fucking fat?"
Eddo Brandes: "Because every time I fuck your wife, she throws me a biscuit."
I hate my sister in law. I think it's because she's the female version of me. But, as much as she repulses me, as much as the sound of her voice irritates me, I must admit, she has an arse that I would love to bury myself balls deep into.
Nope wouldn't do it, play with fire, eventually you'll get burnt
As tempting as it may sound just not the shit it creates...
