Any guy looking to get something for self gratification by either shooting his load into a jar at a sperm bank and getting paid for being a jerk-off OR by sweet talking a female into letting his loser-ass fuck her and when she gets pregnant by him he punks-out and won't daddy-up.
Mr. Squirt, aka sperm-donor, went to the sperm-bank where he made a deposit and got a withdrawal because he needed money to impress the hotty he had a date with that night where he would make another deposit but no withdrawal.

The person that gets a female pregnant but doesn't help her with the child in any way, shape, or form. In some cases they don't acknowledge the child at all.
I saw my sperm donor today. He came by to see my daughter and had the nerve to be empty handed.

A sperm donor is a man who does the bare minimum with his child.
A sperm donor only does what the courts ordered him to do, pay for health insurance and see child 4 days a month. Can't be bothered with a sick child, ER visits, doctors appointments, procedures, lab work or hospital stays.

A boy (not a man), whose sole contribution to the upbringing of his offspring can be repaid by sending him a jizz soaked hankie and a note bearing the words "Now I owe you nothing"(an excellent quote from Salvadore Dali).
1. Adam, my sperm donor, is so lame that he gave the State a false employer name right before christmas.
2. Robert, a boy in a girlie man body, is the avatar of all narcissistic, anhedonic, joyless sperm donors.
3. Elliott, who seemed like a decent sort of fellow, was living a lie every time he called himself a 'father'. In fact, given his many failures to live up to the most minimal definition of the word, the best he could hope for is the ignominious apellation "sperm donor".

A man that fathers a child but basically doesn't do much else.
"Why don't you ask your husband to watch the kids for girls night out?" Girl #1 asks.

"Girl please. He aint no daddy, he's just a sperm donor. I'll see if I can get a sitter." Girl # 2 says.
