They can be distinguished as J.J.I.B. if they wear black rocker-wear, but much more like an emo-style jolog. They come in groups or clusters and can be seen from all corners of the concert grounds, doing emo stuff and jumping around while guitar riffs and head-banging occur. They can be seen with banners or posters with the name of a certain group of J.J.I.B., (e.g., Emo ng Manila; translated as Emo of Manila, Mga Rakista ng Taguig; translated as Rockers of Taguig, etc.)
J.J.I.B. 2: Yeah mehn, tara! Laslas tayo dun!
Fan 1: Yow pare, tignan mo yun oh, mga JJIB.
Fan 2: Yuck pare, ang jologs nila! HAHAHAHA!
