look up any word, like jamflex:
 
1.
Sonpa stands for sex only no public appearances.
It is used to descibe either a female or a male that is used purely for sex and who would not be used as a date either because the person using the sonpa is having an affair or is blatanly too ashamed to be seen dead with the sonpa.
Graham was feeling horny and his wife was playing her frigid best.. It was definately time to visit one of his sonpa's...
