Friction Dance

When 2 people friction dance together without much clothes. First used in an academic article by Thelma about sex & saunas in Scotland.

I am going to Friction Dance all night, so I cant go to the movies tonight.

Friction Fire

1. Where a guy and a girl have raw sex when the girl is not wet enough and it rubs the skin off of one/it hurts really bad and leaves you EXTREMELY sore.

2. When a girl is extremely skinny and has sex

3. Having sex with a red head

"Yeah, Tasha and I tried to GET IT ON, but I didn't feel like fore play and I started a friction fire. Now we can't do it for almost two weeks until my schledium heals.

Fractional Volume of an extraction solvent

Fractional Volume of an extraction solvent is a fraction of the optimum volume of the extraction solvent obtained by dividing the optimum volume of the extraction solvent needed to extract all of the desired solute from a given mass of the solid material into equal smaller volumes for use in separate extraction cycles

If 100ml of an extraction solvent is the optimum volume that would extract all the herbal solute from a medicinal herb, then 100ml/2 gives a fractional volume of an extraction solvent of 50ml, 100ml/3 gives a fraxtional volume of an extraction solvent of 33.333ml

100ml/4 gives a fraxtional volume of an extraction solvent of 25ml,
1/5 x 100 ml gives a fraxtional volume of an extraction solvent of 20ml.

Using fractional volumes of an extraction solvent for extraction purposes gives better extraction yields than using the optimum volume of an extraction solvent as a whole.

fractionophobic

fear of working with fractions

I'm fractionophobic because I have a fear of working with fractions, especially when they are in a math equation.
