The act of engaging in sexual intercourse with a grotty bitch, ie the sort of woman who leaves a snail-trail of cum where ever she goes as a direct result of her indiscriminate promiscuity. Leaving the "dipper" with the stigma of "dipping it in dirty water" and probably a venereal disease too.
"you slept with her!??!! I knew you had been Dipping it in Dirty water! she's a complete slut-bucket!!!"
The ability girls and women have developed to hold several items at once in one hand. The skill has been developed due to the lack of pockets in women's clothing.
