The difference between A Big Saff and a big sucker is that A Big Saff is When a 10/10 female offers the act of intercourse but not love coffee or conversation, and the male subsequently rejects this advance in lieu of talking to another female about animals or coffee grinds while a big sucker is When your girlfriend gives you a blowjob for so long that eventually your dick gets smaller and smaller just like a big lollypop sucker .
A Big Saff Example :
“She begged you for sex? Surely you gave her the slabbcock?!†“ Absolutely not , there was no conversation love or hope of a relationship in sight, I had no option but to pull a big saff on her!â€
a big sucker Example:
Dude, last night my girlfriend gave me a big sucker and now im three inches smaller !
