fartastic 

When you fart very loudly and get a great sense of relief, as the pressure from the gut is released through a great fart.

Aah, that was fartastic, I can relax again now.

Mantastic Number

A song in a musical in which the singers are all male and the song is of a high manful quality; usually involves singing about objectifying women and/or fighting.

The song "Dames" from the Musical "42nd Street" is my favorite mantastic number.

mantastic 

Feeling fantastic after the successful completion of a particularly macho feat.

Following his fifth keg of beer, Kevin ripped the horn off of his pet narwhal, and then nailed his porn-star girlfriend for hours. Subsequently, he felt mantastic.
