We got the comedian at LAX and asked him about Pete's new tat, which seems to read "KNSCP" ... a collection of letters many believe stand for Kim, North, Saint, Chicago and Psalm. BTW ... the initials of their kids are in order of descending age.

It's still unclear whether or not Kim co-signed on the new ink ... or had any idea Pete was doing it at all.

D.L. says it's a troubling decision from the 'SNL' star, given all the hostility between Kanye and his estranged wife's new boyfriend, and he's taking it as a shot across the bow from Pete.

D.L. says it's not fair to Kanye ... in fact, he says it's downright disrespectful.

D.L. has his kids' names tattooed on his body ... another reason why he would be really pissed off if he were in Kanye's shoes, and would have plenty to say about it ... which is interesting, because Kanye has so far remained mum.
