an insult from the 90's but now it's funny because eating a dick is a blowjob but it means to devour a human dick (fully, not a blowjob) and die basically meaning that they'll get death row for cannibalism.
When a horny, slut takes on as many dicks in one day (or night) as she can. Whether it be one on one encounters or gang banging, all count towards her Dick-a-thon.
Rachel took on 26 cocks on Saturday. She’s a true gold medalist in her Dick-a-thon.
I had to go stay with a friend this weekend. I couldn’t get any sleep. My mom was having Dick-a-thon.
a guy who's hot enough that you just wanna go to town on his junkregardless of not knowing a single thing about him
aka: this is another way to categorize the instant hotness/appeal (suckadickability) of a guy
for example, a friend shows you a pic of a guy on facebook or myspace or what have you, and you in turn, can say: "nah, he's not suckadickable (suck-a-dick-a-ble; suck-a-dick-able)", meaning he's not hot enough on a purely physical level
like, the guy is not gonna make you hot enough to take his cock into your eager mouth just like that at first sight
