Non Threatening Penis
A straight male friend who will not try to sleep with a female friend.
He is like a brother, exhibiting completely non-sexual behaviour. He's not necessarily a "nice guy", but just a great friend that has nothing to do with sex.
NTP is the male version of the "fag hag", except both parties are straight.
Most golf clubs hold NTP competitions on one or two par 3s, with entrants stumping up $1 or $2 to make a pool of winnings. The first person to hit the green marks that location and puts their name on a sheet. Anyone who hits it closer moves the marker. At the end of the day, the last person on the sheet (whose tee shot is Nearest The Pin) collects the whole pool of cash money.
Kim: How was golf?
Lee: Pretty rubbish, shot a 95. But I did pick up $200 in the NTP comp. Flushed a sweet 7-iron next to the flag.
Kim: Go you!
This acronym stands for the phrase "No teeth please" inspired bythose who were dissapointed after losing the corn off their cob. One should always say "NTP" right before he receives dome, saftey first!
