Could be a lot of things. Two answers I can think of directly is lack of stretching, or you have some sort of vitamin/nutrient deficiency.

Do you get muscle tightness randomly through out the day? Or after playing sports?

I will move this to fitness section so you might receive some more answers, this isn't exactly a "men related condition"

the tightness usually hits me during the sporting activities, but has hit randomly during the day, i do stretch every time, more so since all the spasm/tightness started occurring. list of tightness locations(neck, right tricep, left calf, lower back, glutes)

So then for instance, you could be walking along, no worries or troubles in the world at the moment and not doing any physical activity, and then all of a sudden your calf or other various parts would suddenly contract and tighten up?

What sports do you do, how frequently and how long? What is your diet like on a typical day and do you eat/drink anything in particular before or after your sport activities?

I'm not sure what causes the tightness/cramps/spasms. However, I know that eating bananas will definitely reduce how prone u are to cramps due to how much potassium they have

let me suggest self-myofascial release or foam rolling. there is quite a bit of literature out there on how to do it. basically you are working out all the "knots" in your muscle fibers and is used as a pre-stretch exercise as well as a cool dwon. this technique will allow you to be loose at the time of stretching and allow great rang of motion on static stretches.
