Similar to a decathlon in that there are a series of events.. except the events involved include riding dick & the point system is calculated by the amount of orgasms on both ends.
Trish, “Omg Vicky I haven’t worked out in forever.. idk if I’ll be able to keep up with the 5k tomorrow”
Vicky, “Trish! Didn’t you just tell me you completed a Dickathlon this weekend?? I am sure you are ready!”
Trish, “Oh yeah I forgot about that! I did out score Brandon at the Dickathlon! I am totally ready!”
Mainly another word for a dick head. Like a unicorn, dickacorns are thought to have a dick smack dab in the middle of there forehead. They are an all male species (w/t a few exceptions) but unlike the gracefull unicorns who are (sadly) not real/extinct, the dickacorns (sadly) still exist.
