HAHEH - When something is so funny you laugh until your face turns r

When something is so funny you laugh until your face turns red and your friend asks if you’re okay and you just go HAHEH.

I laughed so hard my face turned red HAHEH

My friend told a joke and I laughed until I turned red HAHEH

I saw my dog fall off the couch and I laughed until I turned red HAHEH
