A song by the rapper Lil Wayne. Some people believe the song is saying milli like a million but its really a loop saying im ill (if you take the last i and the first m in the word it gives you im and then ill is left over.
At the begenning of the song it says Im Ill.
(milli is just what word is made when im ill is looped and the voice on its changed.)
the act of prematurely ejaculating, usually due to extreme lack of sex or the opportunity to fool around with someone way out of one's league... as in only lasting a millisecond. Athough this is usually rather embarrassing for the person who "millied", it should always be brought up by friends in as many conversations as possible as a reminder.
"hey man, how'd your date with that hottie go?" "eh, not good." "did you milli again?" "I CAME EARLY ONE TIME!! LET IT GO ALREADY!!"
