Regex for a word that repeats only the chars i provide?

Ok so what im trying to do is match words like "lol" and "lollll" and "llllol" and "llllooooollll" and "loool" but not "pfftlol" or "lolpfft" etc.

my current code is

_.each(req.room._settings.automod.cussing.words, function(word)
{
    if(req.message.text.match(new RegExp('\\b'+word.split('').join('+?')+'\\b', 'gi')))
    {
        if(req.user && req.user.cache.automod.cussing === 0)
        {
            req.user.cache.automod.cussing = 1;
            req.write(req.user.name+", Please refrain from cussing in your messages this is your first and only warning next time you will be deleted.");
            req.room.delLastUser(req.user.name, 1);
        }
        else
        {
            req.room.delLastUser(req.user.name, 1);
        }
    }
});

and out of it 

req.message.text.match(new RegExp('\\b'+word.split('').join('+?')+'\\b', 'gi'))

also lets say that req.room._settings.automod.cussing.words is ['lol','what'] since i dont want to list actual cuss words

and req.message.text is 'hah lollll hey'

also this is going through an _.each statement or foreach I'm using NodeJS

right now it returns the word as long as it partially matches

anyone know what I'm doing wrong?

The answer from Ismael Miguel is correct

/\b(l)+(o)+(l)+\b/

which looks like this in my code

var reg = '\\b('+cuss.split('').join(')+(')+')+\\b'; req.message.text.match(new RegExp(reg, 'gi'));

Try this regex:

/.*\b(l+o+l+)\b.*/


var strings = ["who is lol", "looolll am i", "rofl llllooll", "pfftlol", "lolwho", "anotherlol", "lllllol hehe"];

for(var i = 0; i < strings.length; ++i){
var match = strings[i].match(/.*\b(l+o+l+)\b.*/);
  if (match)
    document.write( match[0] + "<br>") ;
}
