ED = Eat a dick (usually used after a concentration of hormone. People put this so guys don't come on their thread and say things like "I would change the dose to.." or "Isn't that too much..."). People put this in advance just as a warning to idiots.
EOD = Eat our dicks (same as above, but the user of this term usually believes that everyone else agrees with him).
So before you ask these kinda questions, read the stickys..EOD.
