two-thirdy 

Similar to "half on" but with more expressed arousal. Can be caused by decreased lack of arousal from anxiety or from incomplete arousal (as in the case of a rodeo).

As I was frantically losing my hard-on, I saved it and maintained a two-thirdy. Whew! That was close.

two-thirds-your-age-plus-six 

It's a rule for the range of people you can date.
If you are 99 years old...
99*(2/3)+7 = 73
73 - 99 years is the range of people you can date younger than you.

examples:

10 years = 10-13.6
14 years = 14-16.3
16 years = 16-17.6
18 years = 18-19
20 years = 20-20.3
30 years = 27-30
50 years = 40.3-50
99 years = 73-99

You can't date her, she's 33 and you 23... use the "two-thirds-your-age-plus-six" rule dude.

One-Two Thirds

A form of digitallighting common on Discord servers and similar platforms, where two or more participants coordinate to target a single person, systematically undermining their credibility, twisting their words, and provoking reactions. The name reflects the imbalance: one victim versus two (or more) aggressors acting as a bloc. The tactic often involves one person playing “reasonable” while another attacks, or alternating who responds to prevent the target from keeping up. The goal is to create the appearance of overwhelming consensus against the target, making them seem irrational or isolated, and to increase the likelihood of a reactive outburst that can be reported as harassment. One‑Two Thirds weaponizes numbers, turning social dynamics into a trap.

One-Two Thirds Example: “In the server, two users tag‑teamed her: one asked ‘innocent’ questions, the other called her answers delusional. When she snapped, both reported her. Classic One‑Two Thirds.”

thirty-two 

when only one partner gets their anus licked in preparation for anal sex; performing only half of a sixty-four (sixty-four is like 69 but only the ass is eaten)

He is a strictly a power top so they never sixty-four, but he prepares his partners well by doing a thirty-two.
