there are several meanings:
1.) to ejaculate 2.) an insult, like asshole or fart knock 3.) to have feces on one's penis after anal
4.) when the colon is connected to the urethra, causing the man to defecate from his penis
5.) to excrete out a man's penis
1.) oh baby, i'm going to dickshit in you!
2.) lick my butthole you dickshit
3.) eww girl, you gave me a dickshit
examples 4 and 5 can be heard on the Vonal-Ksz demo "Diced Uterus in Rectal Slop"
A word used to describe the sort of person who doesn't just deserve one swear word but two so by combinding the word dick and shit creates dickshit the final form of swear words.
