Jake Paul wants to beat the living dog snot out of Soulja Boy ... but it's not out of hate -- it's because the YouTube superstar wants to make him relevant again!!!
TMZ Sports spoke with Paul about calling out Mr. "Pretty Boy Swag" for an epic celeb boxing match ... and he says it may not happen because Soulja Boy is SCARED of getting KO'd!!!
But, 22-year-old Paul tells us he's actually trying to HELP Soulja out ... 'cause he thinks the fight will give him major clout and give him a new audience.
