flash blood 

The act of sharing ones blood while high on heroin with another to get them high. If one junkie has used and the other has no heroin, the one who is high will draw their blood into a syringe and inject the non-holding junkie with the blood to get them high. A new practice that will spark the spread of aids and hepatitis like wildfire.

Mambasa, flash blood me, I aint holding and am getting dope sick.

Flesh and Blood 

From Shakespeare's Hamlet this term means 'one's family'. Your brother, sister, mom or dad would be your own flash and blood.

If you dare touch my flesh and blood, I will bring my hammer down on you like Thor gone berserk.

Blood Flush 

When a woman's menstrual cycle cleanses her vagina for the next sexual partner.

It represents a much needed resetting of the vagina.

Nah we can't have sex for another week. She fucked her ex. I need that bitch to have a blood flush.

Testosterone Flashflood 

What happens when two or more males suddenly have an overpowering and uncontrollable urge to assert their dominance over the other, and innocents are caught in the crossfire.

Adam: Hey, did you hear what happened in the workshop yesterday? Paul and Logan got into a violent screaming match, and it nearly turned into a full-fledged fight!

Austin: Yeah, man, I was there. Total testosterone flashflood. A freshman girl freaked out and started crying it was that intense!

flashblonde 

A flashback of a blonde moment you or someone else had.

Usually the person flashblonding is thinking about it and involuntarily smiling, which to everyone else is odd because it seems the person is smiling for no apparent reason.

Delia: During the Great Depression, there were many homos.
Sophie: Do you mean hobos?
D: Oh! HAHA, yeah!
...and hour later...
~Sophie is thinking back to this convo. and laughs randomly~
D: You're having a flashblonde, aren't you?
S: haha, yep, you caught me.
