The owner of the other team rejected and responded with "LOL"
If I'm responding to a long-time friend I'm in a league with, then sometimes I'll comment "lol" on a trade offer. But if it's a league I'm in with strangers (FFPC, for example), then I almost always bite my tongue on offers I find insulting. In FFPC, right before the Thanksgiving trade deadline, I sent what I thought was a reasonable offer (my Roschon Johnson for his Jaylen Warren), only to get a rejection with the comment, "bro lolol." Right after Jeudy was traded, same guy sent me an offer of his Jeudy for my superflex 1.08, and it took everything I had to just hit "reject" with no comment, even though I so badly wanted to respond with "bro lolol."
